feat: pump tracker, photo log, milk stock, medication profiles, calendar, reminders, audit log, edit events

New pages:
- /calendar — monthly grid with event dots, day detail on tap
- /medications — CRUD for medication profiles (presets + custom, dose/unit/intervals/crisis mode)
- /milk — milk stock management with location-based expiry, alerts, mark-as-used
- /reminders — recurring medication reminder CRUD with Pushover notifications

New APIs:
- /api/medication-profiles — profiles CRUD + last-intakes endpoint (auto-seeds 10 presets per family)
- /api/milk — milk stock CRUD with auto-calculated expiry
- /api/reminders + /api/reminders/check — reminder CRUD + cron-callable check endpoint
- /api/upload — multipart photo upload to public/uploads/
- /api/invite/send-email — email invitation with family invite link
- /api/admin/audit — last 100 audit log entries (superadmin only)

Event modal improvements:
- PUMP event type (side selector + volume + timer)
- MEDICATION: profile chip picker, next-dose timing status, crisis mode toggle
- Photo attachment (upload + thumbnail preview)
- Datetime inputs split into date + time (iOS Safari datetime-local fix)
- Edit mode via initialEvent prop (pre-fills all fields, saves via PATCH)
- Timer now shows h:mm:ss when >= 1 hour

Timeline:
- Modify button opens pre-filled edit modal per event
- Photo thumbnail in expanded view

Dashboard:
- PUMP in quick-log
- Medication status card (too-soon / available with next-dose time)

Schema additions: MedicationProfile, MedcationReminder, MilkStock, AuditLog models
