feat(analytics): add custom event tracking to Storage app

Add StorageEvents helper (11 events) and integrate tracking into:
- Files store: download, delete, favorite, view mode toggle
- Shared page: share link copy/delete
- Trash page: restore, empty trash
- Search page: search performed with results count

Updates ManaScore analytics from 3/5 to 4/5 (customEvents: true).
