feat: Phase A backend — notes CRUD, detail endpoints, dashboard fix

- Create kanzlai.notes table (polymorphic FK with CHECK constraint, partial indexes, RLS) - Add Note model, NoteService (ListByParent, Create, Update, Delete), and NoteHandler with endpoints: GET/POST /api/notes, PUT/DELETE /api/notes/{id} - Add GET /api/deadlines/{deadlineID} detail endpoint - Add GET /api/appointments/{id} detail endpoint - Add GET /api/case-events/{id} detail endpoint (new CaseEventHandler) - Fix dashboard query: add case_id to upcoming_deadlines SELECT, add id and case_id to recent_activity SELECT - Register all new routes in router.go
