feat(digiserver-v2): port edited media report and deploy badge features from standalone

- Added edited_media_report route to players blueprint with tabular report view
- Created edited_media_report.html template with summary stats, dark mode, print/PDF support
- Created _deploy_badge.html partial template for deployment status display
- Added deployment status column and badge CSS to players_list.html
- Added 'View Report' button to manage_player.html next to 'View All Edited Media'
- Fixed api.py receive_edited_media with robust content lookup:
  - Fallback content lookup by regex path matching (edited_media/<id>/)
  - Fallback via PlayerEdit record if direct lookup fails
  - First-edit original file preservation (moves original to versionized folder)

Enterprise-specific features (portal SSO, internal sync, playlist permissions, WAL mode) are preserved unchanged.
