fix(radarr): improve event type parsing and grab event validation

- Fix string-based event type parsing (grabbed, downloadFolderImported, etc.)
- Filter grab events to only count actual downloads with metadata
- Fix JSON parsing errors for dict-type event data
- Enhanced chronological processing for accurate import date detection
- Validate grab events require sourceTitle or indexer info

Fixes issue where library addition events were mistaken for download grabs,
ensuring only real download timestamps are used for
