Comprehensive fix for test suite warnings across multiple issue test files:
### SQLite3 Date Adapter Warnings (Python 3.12)
- Fixed 101 warnings in Issue 113 (activity_tracker.py)
- Fixed 55 warnings in Issue 114 (allocation_engine.py)
- Fixed 148 warnings in Issue 122 (worktime_tracker.py + test file)
- Fixed 18 warnings in Issue 124 (day_wrapup_commands.py + worktime_tracker.py)
### Pytest-asyncio Configuration
- Added asyncio_default_fixture_loop_scope = function to pytest.ini
- Eliminates pytest-asyncio deprecation warning
### Runtime Warnings for Unawaited Coroutines
- Fixed 2 warnings in Issue 59 (gitea plugin async mocking)
- Enhanced AsyncTestCase with better coroutine cleanup
- Improved async mock management in test utilities
### Technical Changes
- Convert Python date/datetime objects to ISO strings before SQLite queries
- Use .isoformat() with defensive hasattr() checks for backward compatibility
- Simplified async test mocking to avoid coroutine creation
- Enhanced cleanup_async_mocks() function for comprehensive cleanup
### Results
- Before: ~324 warnings across test suite
- After: 0 warnings - completely clean test suite
- All 216+ tests pass with zero warning noise
