feat(core): standardize SeriesApp to use key as primary identifier

Task 2.1 - Update SeriesApp to Use Key for All Operations

Changes:
- Added 'key' field to DownloadStatusEventArgs and ScanStatusEventArgs
- Updated download() method docstrings to clarify key vs folder usage
- Implemented _get_serie_by_key() helper method for series lookups
- Updated all event emissions to include both key (identifier) and folder (metadata)
- Enhanced logging to show both key and folder for better debugging
- Fixed test mocks to include new key and item_id fields

Benefits:
- Consistent series identification throughout core application layer
- Clear separation between identifier (key) and metadata (folder)
- Better debugging with comprehensive log messages
- Type-safe lookups with Optional[Serie] return types
- Single source of truth for series lookups

Test Results:
- All 16 SeriesApp tests pass
- All 562 unit tests pass with no regressions
- No breaking changes to existing functionality

Follows:
- PEP 8 style guidelines (max 79 chars per line)
- PEP 257 docstring standards
- Project coding standards (type hints, error handling, logging)
