Phase 5: Frontend - Use key as primary series identifier

- Updated app.js to use 'key' as primary series identifier
  - selectedSeries Set now uses key instead of folder
  - createSerieCard() uses data-key attribute for identification
  - toggleSerieSelection() uses key for lookups
  - downloadSelected() iterates with key values
  - updateSelectionUI() and toggleSelectAll() use key

- Updated WebSocket service tests
  - Tests now include key and folder in broadcast data
  - Verified both fields are included in messages

- No changes needed for queue.js and other JS files
  - They use download item IDs correctly, not series identifiers

- No template changes needed
  - Series cards rendered dynamically in app.js

All 996 tests passing
