Implement remaining handlers and fix admin login

- Fix admin login bcrypt hash in database migrations
- Add static data handler (GET /api/static_data/, POST /api/static_data/refresh/)
- Add user handler (list users, get user, list profiles in shared residences)
- Add generate tasks report endpoint for residences
- Remove all placeholder handlers from router
- Add seeding documentation to README

New files:
- internal/handlers/static_data_handler.go
- internal/handlers/user_handler.go
- internal/services/user_service.go
- internal/dto/responses/user.go

+
+Seed files are located in `seeds/`:
+- `001_lookups.sql` - Lookup tables (residence types, task categories, priorities, etc.)
+- `002_test_data.sql` - Test users, residences, tasks, contractors, etc.

+- 4 contractors with specialties
+- 10 tasks across residences
+- Documents/warranties

 This is a full rewrite that maintains API compatibility. The mobile clients (KMM) work with both versions without changes.
