Fix medication system and rename to Synculous.

- Add all 14 missing database tables (medications, med_logs, routines, etc.)
- Rewrite medication scheduling: support specific days, every N days, as-needed (PRN)
- Fix taken_times matching: match by created_at date, not scheduled_time string
- Fix adherence calculation: taken / expected doses, not taken / (taken + skipped)
- Add formatSchedule() helper for readable display
- Update client types and API layer
- Rename brilli-ins-client → synculous-client
- Make client PWA: add manifest, service worker, icons
- Bind dev server to 0.0.0.0 for network access
- Fix SVG icon bugs in Icons.tsx
- Add .dockerignore for client npm caching
