fix: login loop and repeated medication notifications

- Fix login loop: secure cookie detection now uses x-forwarded-proto/origin
  headers to correctly identify HTTPS requests through Tailscale Funnel
- Add credentials: include to login/register fetch calls
- Verify session after login/registration before redirecting to prevent race conditions
- Fix repeated medication reminders: isDue() now matches exact minute instead of
  5-minute tolerance window, preventing duplicate notifications when sender runs
  every minute
- Add tests for cookie security and notification scheduling
- Extract isDue() to separate module for better testability

+# Design: 8 New Features for Next Step
+
+**Date:** 2026-03-01
+**Priority:** Urgent
+**Scope:** Medium (3-5 days)
+**Target Users:** End users (patients & family caregivers)
+
+---
+
+## Established Patterns (must follow)
+
+All new features must follow these exact conventions from the codebase:
+
+### File Patterns
+- **Pages:** `src/app/(app)/<feature>/page.tsx` — `'use client'`, uses `useApp()` for workspace, `Header` + `PageContainer` layout
+- **API routes:** `src/app/api/workspaces/[id]/<feature>/route.ts` — uses `withAuth`, `checkWorkspaceAccess`, `canEdit`, Zod validation, audit log on writes
+- **Components:** `src/components/<feature>/ComponentName.tsx` — `'use client'`, uses UI kit (`Card`, `Button`, `showToast`)
+- **Validation:** `src/lib/validation/schemas.ts` — Zod schemas with type exports
+- **Dexie tables:** `src/lib/sync/db.ts` — interface + table definition, bump version
+- **Sync ops:** `src/lib/sync/manager.ts` — add entity types and op handlers
+
+### UI Patterns
+- Colors: `primary-*` (sage green), `secondary-*` (warm stone), `accent-*` (terracotta), `alert-*` (soft red), `cream-*` (warm neutral)
+- Semantic: `bg-background`, `bg-surface`, `bg-muted`, `border-border`
+- Cards: `<Card>` with `shadow-card`, `rounded-card` (20px)
+- Touch: `min-h-touch` (48px), large tap targets
+- Typography: `font-display` for headings, `text-secondary-900` for titles, `text-secondary-500` for meta
+- Icons: `lucide-react`, 6x6 default, stroke color matching text
+- States: `LoadingState`, `EmptyState`, `ErrorState` from `@/components/ui`
+- Toast: `showToast('message', 'success'|'error')`
+- Page structure: `<Header title="X" />` then `<PageContainer className="pt-4 space-y-6">`
+
+### API Patterns
+```typescript
+export const GET = withAuth(async (req: AuthenticatedRequest, { params }) => {
+  const { id: workspaceId } = await params
+  const access = await checkWorkspaceAccess(workspaceId, req.session.user.id)
+  if (!access) return NextResponse.json({ error: 'Access denied' }, { status: 403 })
+  // ... logic
+})
+
+export const POST = withAuth(async (req: AuthenticatedRequest, { params }) => {
+  const { id: workspaceId } = await params
+  const access = await checkWorkspaceAccess(workspaceId, req.session.user.id)
+  if (!access || !canEdit(access.role)) return NextResponse.json({ error: 'Access denied' }, { status: 403 })
+  const body = await req.json()
+  const result = schema.safeParse(body)
+  if (!result.success) return NextResponse.json({ error: 'Invalid input', details: result.error.flatten() }, { status: 400 })
+  // ... create + audit log
+})
+```
+
+### Data fetch pattern (pages)
+```typescript
+// 1. useLiveQuery from Dexie for offline-first
+const localData = useLiveQuery(() => db.table.where('workspaceId').equals(id)..., [id])
+// 2. Also fetch from server
+const fetchData = useCallback(async () => { ... }, [currentWorkspace.id])
+// 3. Combine: prefer server, fallback to local
+const data = serverData.length > 0 ? serverData : localData || []
+```
+

+## UI/Page Design
+
+### Navigation Change
+
+The bottom nav currently has 5 items. With 8 new features, the "More" (Settings) tab becomes a hub. The new features are accessed via:
+
+- **Today page** surfaces: Temperature, Weight (quick log cards), upcoming tasks, next milestone
+- **Bottom nav** stays as-is (Today, Appts, Meds, Symptoms, More)
+- **"More" page** (`/settings`) becomes a menu with sections:
+  - Account & Settings (existing)
+  - **Health Tracking**: Temperature, Weight, Lab Results
+  - **Care Team**: Contact Directory, Caregiver Tasks
+  - **Treatment**: Timeline, Medical Documents
+  - **Safety**: Drug Interactions
+
+### Feature 1: Temperature Log — `/temperature`
+
+**Page structure:**
+- Header: "Temperature" with History icon (right)
+- Quick log card: big number input (keyboard type=decimal), method selector (4 pill buttons: Oral/Forehead/Ear/Armpit), optional notes, "Log Temperature" button
+- **Fever alert banner**: if last reading >= 38.0°C, show red alert card: "FEVER DETECTED — 38.3°C" with "Call Clinic" button using `tel:` link from workspace.clinicPhone
+- Last 7 days: mini chart (horizontal bar or sparkline showing daily temps)
+- Recent readings: list of TemperatureCard components
+
+**Components:**
+- `src/components/temperature/TempQuickLog.tsx` — number input, method pills, submit
+- `src/components/temperature/TempCard.tsx` — single reading display
+- `src/components/temperature/TempChart.tsx` — 7-day chart (pure CSS bars, no lib needed)
+- `src/components/temperature/FeverAlert.tsx` — red alert banner with call button
+
+**Key UX:**
+- Default unit based on locale (°C for AU). Display toggle °C/°F.
+- 38.0°C threshold → yellow warning. 38.5°C → red emergency.
+- Number input: show decimal keyboard on mobile via `inputMode="decimal"`
+
+### Feature 2: Contact Directory — `/contacts`
+
+**Page structure:**
+- Header: "Care Team" with Plus icon (right)
+- Category filter tabs: All / Oncology / Hospital / Pharmacy / Insurance / Family
+- Emergency contacts section at top (if any marked isEmergency)
+- Contact cards: avatar circle (first letter), name, role, big green CALL button
+- Tap card → expand to show all details
+
+**Components:**
+- `src/components/contacts/ContactCard.tsx` — name, role, call button, expandable
+- `src/components/contacts/ContactForm.tsx` — modal form for create/edit
+- `src/components/contacts/CategoryTabs.tsx` — horizontal scroll filter
+
+### Feature 3: Weight Log — `/weight`
+
+**Page structure:**
+- Header: "Weight" with History icon
+- Quick log: large number input (kg), small toggle for kg/lbs, notes, "Log Weight" button
+- Trend card: 30-day line chart (CSS-based or simple SVG)
+- Alert card: if weight changed >2kg in 24hrs, show warning
+- Recent readings: list
+
+**Components:**
+- `src/components/weight/WeightQuickLog.tsx`
+- `src/components/weight/WeightCard.tsx`
+- `src/components/weight/WeightChart.tsx` — simple SVG line chart
+- `src/components/weight/WeightAlert.tsx` — rapid change warning
+
+### Feature 4: Treatment Timeline — `/timeline`
+
+**Page structure:**
+- Header: "Treatment Journey" with Plus icon
+- Progress bar at top: "Cycle 4 of 6 — 67% Complete" (calculated from completed/total milestones)
+- Vertical timeline: milestones sorted by plannedDate
+  - Left: date
+  - Center: dot (green=completed, blue=scheduled, orange=delayed, gray=cancelled)
+  - Right: title, type badge, notes
+- Bottom: "Add Milestone" button
+
+**Components:**
+- `src/components/timeline/TimelineView.tsx` — vertical timeline layout
+- `src/components/timeline/MilestoneCard.tsx` — single milestone
+- `src/components/timeline/ProgressBar.tsx` — overall progress
+- `src/components/timeline/MilestoneForm.tsx` — modal for create/edit
+
+**Key UX:**
+- Completed milestones have a subtle celebration effect (checkmark)
+- Auto-scroll to "now" position in timeline
+- Color by type: blue=chemo, orange=surgery, purple=radiation, green=scan
+
+### Feature 5: Caregiver Tasks — `/tasks`
+
+**Page structure:**
+- Header: "Tasks" with Plus icon
+- Filter tabs: My Tasks / All / Done
+- Task list grouped by priority (Urgent at top)
+- Each task: title, assignee avatar, due date, category chip, priority indicator
+- Swipe right to complete (or tap checkbox)
+- FAB or bottom "Add Task" button
+
+**Components:**
+- `src/components/tasks/TaskCard.tsx` — task with checkbox, assignee, due date
+- `src/components/tasks/TaskForm.tsx` — modal with assignee picker (workspace members)
+- `src/components/tasks/TaskFilters.tsx` — status/assignee filter
+
+**Key UX:**
+- "Quick add" templates: "Pick up prescription", "Drive to appointment", "Prepare meals"
+- Overdue tasks highlighted in accent/red
+- Completion shows brief success animation
+
+### Feature 6: Lab Results — `/lab-results`
+
+**Page structure:**
+- Header: "Lab Results" with Plus icon
+- Tab: Recent / Trends
+- **Recent tab:** List of lab result cards sorted by date, showing panel name, date, flag count
+- **Trends tab:** Marker selector (dropdown: WBC, RBC, Platelets, Hemoglobin, etc.) → SVG line chart with reference range shaded
+- Add result: modal with panel template selector (CBC template pre-fills common markers)
+
+**Components:**
+- `src/components/labs/LabResultCard.tsx` — panel summary with flagged values highlighted
+- `src/components/labs/LabResultForm.tsx` — panel selector + marker rows (marker/value/unit/range)
+- `src/components/labs/LabTrendChart.tsx` — SVG chart with ref range shading
+- `src/components/labs/MarkerRow.tsx` — single marker with flag coloring
+
+**Key UX:**
+- Pre-built panel templates: CBC (WBC, RBC, Hemoglobin, Hematocrit, Platelets), CMP, Liver, Tumor Markers
+- Flag colors: green=normal, yellow=borderline, red=out of range, dark red=critical
+- "Share with doctor" → links to print page
+
+### Feature 7: Medical Documents — `/documents`
+
+**Page structure:**
+- Header: "Documents" with Plus icon (upload)
+- Category filter: All / Lab Reports / Scans / Insurance / Prescriptions
+- Document grid: 2 columns, thumbnail (icon by type), title, date, category badge
+- Tap → full-screen viewer (PDF in iframe, images native)
+- Upload: file picker, category select, title, date, notes
+
+**Components:**
+- `src/components/documents/DocumentCard.tsx` — thumbnail, title, category badge
+- `src/components/documents/DocumentUpload.tsx` — file picker modal
+- `src/components/documents/DocumentViewer.tsx` — full-screen view
+
+**Key UX:**
+- Max file size: 10MB
+- Accepted types: PDF, JPG, PNG
+- Expiry badge on insurance cards approaching expiry
+- No offline sync for documents (too large) — show "Requires internet" badge
+
+### Feature 8: Drug Interaction Checker — `/meds` (integrated)
+
+**Not a separate page.** Integrated into the medications section:
+- "Check Interactions" button on meds list page
+- Results shown as a modal/sheet with severity-colored cards
+- Warning banner on individual medication detail pages if interactions exist
+
+**Implementation approach (simplified, no external API for v1):**
+- Ship with a local lookup table of ~200 common chemo drug interactions (JSON file)
+- `src/lib/interactions/checker.ts` — pure function that takes med names, returns known interactions
+- `src/lib/interactions/data.ts` — curated interaction database
+- Can upgrade to external API (OpenFDA/RxNorm) later
+
+**Components:**
+- `src/components/medications/InteractionCheck.tsx` — button + results modal
+- `src/components/medications/InteractionCard.tsx` — severity badge, description
+- `src/components/medications/InteractionBanner.tsx` — warning on med detail
