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

Browse Source 
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)

**Status:** ✅ COMPLETED
**Implementation Details:**
- **Import Added**: Imported `Serie` class from `src.core.entities.series` for type hints
- **DownloadStatusEventArgs Updated**:
- Added `key: Optional[str] = None` parameter to constructor
- Updated docstring to clarify `serie_folder` is "metadata only, used for file paths"
- Updated docstring to clarify `key` is "Serie unique identifier (provider key, primary identifier)"
- All event emissions now include both `key` and `folder` for complete context
- **ScanStatusEventArgs Updated**:
- Added `key: Optional[str] = None` parameter to constructor
- Updated docstring to clarify `folder` is "metadata only"
- Updated docstring to clarify `key` is "Serie unique identifier if applicable (provider key, primary identifier)"
- **download() Method Enhanced**:
- Updated docstring with comprehensive parameter documentation
- Added explicit note: "The 'key' parameter is the primary identifier for series lookups. The 'serie_folder' parameter is only used for filesystem operations."
- All logging statements now include both `key` (for identification) and `folder` (for context)
- All event emissions include both `key` and `folder`:
- Download started event
- Download progress events
- Download completed event
- Download failed event
- Download error event
- **Helper Method Added**:
- Implemented `_get_serie_by_key(key: str) -> Optional[Serie]` method
- Uses `self.list.get_by_key(key)` for lookups (key-based, not folder-based)
- Comprehensive docstring explaining this is the primary lookup method
- Properly typed with `Optional[Serie]` return type
- **Logging Improvements**:
- All download-related logs now show both key and folder: `"Starting download: %s (key: %s) S%02dE%02d"`
- Provides better context for debugging and monitoring
- Follows PEP 8 line length guidelines (max 79 characters)
- **Code Quality**:
- All docstrings follow PEP 257 standards
- Type hints used throughout
- Lazy logging with % formatting instead of f-strings
- Proper line length (max 79 characters per PEP 8)
- Two blank lines between class definitions
- **Test Updates**:
- Updated `tests/unit/test_download_progress_websocket.py`
- Fixed `MockDownloadArgs` class to include `key` and `item_id` fields
- All mock download event emissions now include `key` parameter
- Ensures backward compatibility and proper event structure
- **Test Results**:
- All 16 SeriesApp tests pass successfully
- All 562 unit tests pass with no regressions
- Test coverage maintained at high level
- No breaking changes to existing functionality
**Benefits of This Change**:
1. **Consistency**: Series identification is now consistent throughout the core application layer
2. **Clarity**: Clear separation between identifier (`key`) and metadata (`folder`)
3. **Debugging**: Logs and events show both identifiers for better troubleshooting
4. **Type Safety**: Proper type hints with `Optional[Serie]` return types
5. **Maintainability**: Single source of truth for series lookups via `_get_serie_by_key()`
6. **Backward Compatibility**: All existing functionality preserved, tests pass
