Implement reminders system with full CRUD and background processors

- Reminders service: create, update, delete, complete, snooze, dismiss
- List with filters (status, priority, assignee, entity, date range)
- My/overdue/upcoming convenience endpoints
- BullMQ processors: auto-follow-up creation (BR-060) and overdue notifications
- Snooze with presets (1h, 4h, tomorrow, next week) and custom datetime
- Un-snooze logic: snoozed reminders auto-revert to pending when snooze expires
- UI: filterable list with my/all toggle, priority badges, overdue indicators
- Permission-gated: view_own, view_all, create, assign_others
- Entity linking: reminders can link to clients, interests, or berths
