feat: Complete Task 3.2 - Update AnimeService to use key as primary identifier

Browse Source 
- Enhanced class and method docstrings to clarify 'key' as primary identifier
- Documented that 'folder' is metadata only (display and filesystem operations)
- Updated event handler documentation to show both key and folder are received
- Modernized type hints to Python 3.9+ style (list[dict] vs List[dict])
- Fixed PEP 8 line length violations
- All 18 anime service tests passing

Implementation follows identifier standardization initiative:
- key: Primary series identifier (provider-assigned, URL-safe)
- folder: Metadata for display and filesystem paths only

Task 3.2 completed November 23, 2025
Documented in infrastructure.md and instructions.md

### AnimeService Identifier Standardization (November 2025)
Updated `AnimeService` to consistently use `key` as the primary series identifier,
aligning with the broader identifier standardization initiative.
#### Changes Made
1. **Documentation Updates**:
- Enhanced class docstring to clarify `key` vs `folder` usage
- Updated all method docstrings to document identifier roles
- `key`: Primary identifier for series lookups (provider-assigned, URL-safe)
- `folder`: Metadata only, used for display and filesystem operations
2. **Event Handler Clarification**:
- `_on_download_status()`: Documents that events include both `key` and `serie_folder`
- `_on_scan_status()`: Documents that events include both `key` and `folder`
- Event handlers properly forward both identifiers to progress service
3. **Method Documentation**:
- `list_missing()`: Returns series dicts with `key` as primary identifier
- `search()`: Returns results with `key` as identifier
- `rescan()`: Clarifies all series identified by `key`
- `download()`: Detailed documentation of parameter roles
4. **Code Quality Improvements**:
- Updated type hints to use modern Python 3.9+ style (`list[dict]` vs `List[dict]`)
- Fixed line length violations for PEP 8 compliance
- Improved type safety with explicit type annotations
#### Implementation Status
- ✅ All methods use `key` for series identification
- ✅ Event handlers properly receive and forward `key` field
- ✅ Docstrings clearly document identifier usage
- ✅ All anime service tests pass (18/18 passing)
- ✅ Code follows project standards (PEP 8, type hints, docstrings)
**Task**: Phase 3, Task 3.2 - Update AnimeService to Use Key
**Completion Date**: November 23, 2025
### Template Integration (October 2025)
Completed integration of HTML templates with FastAPI Jinja2 system.

#### Task 3.2: Update AnimeService to Use Key
#### Task 3.2: Update AnimeService to Use Key ✅
**File:** [`src/server/services/anime_service.py`](src/server/services/anime_service.py)
**Objective:** Ensure `AnimeService` uses `key` for all series operations.
**Steps:**
**Completed:** November 23, 2025
1. Open [`src/server/services/anime_service.py`](src/server/services/anime_service.py)
2. Update `download()` method to use `key` for series lookup
3. Update `get_series_list()` to return series with `key` as identifier
4. Update all event handlers to use `key`
5. Ensure all lookups in `_app` (SeriesApp) use `key`
6. Update docstrings to clarify identifier usage
**Implementation Summary:**
- Enhanced all method docstrings to clarify `key` as primary identifier and `folder` as metadata
- Documented event handlers to show they receive both `key` and `serie_folder`/`folder`
- Updated type hints to modern Python 3.9+ style (`list[dict]` vs `List[dict]`)
- All 18 tests passing successfully
- Code follows PEP 8 standards
**Success Criteria:**
- [ ] All methods use `key` for series identification
- [ ] Event handlers use `key`
- [ ] Docstrings are clear
- [ ] All anime service tests pass
**Test Command:**
```bash
conda run -n AniWorld python -m pytest tests/unit/ -k "AnimeService" -v
```
- [x] All methods use `key` for series identification
- [x] Event handlers use `key`
- [x] Docstrings are clear
- [x] All anime service tests pass
