Add user settings, audit log, berth CRUD, and missing endpoints

- PATCH /api/v1/me: self-service profile update (name, phone, timezone)
- User settings page with profile editor + notification preferences
- Audit log API with filtering (entity, action, user, date range)
- Audit log page with search, entity type, and action filters
- Berth create/delete: POST /api/v1/berths + DELETE /api/v1/berths/[id]
- Client duplicates endpoint: GET /api/v1/clients/duplicates?name=
- Replace settings and audit stub pages with real implementations
