fix: resolve all failing tests (701 tests now passing)

- Add missing src/server/api/__init__.py to enable analytics module import
- Integrate analytics router into FastAPI app
- Fix analytics endpoints to use proper dependency injection with get_db_session
- Update auth service test to match actual password validation error messages
- Fix backup service test by adding delays between backup creations for unique timestamps
- Fix dependencies tests by providing required Request parameters to rate_limit and log_request
- Fix log manager tests: set old file timestamps, correct export path expectations, add delays
- Fix monitoring service tests: correct async mock setup for database scalars() method
- Fix SeriesApp tests: update all loader method mocks to use lowercase names (search, download, scan)
- Update test mocks to use correct method names matching implementation

All 701 tests now passing with 0 failures.
