feat(ContentManager): Display friendly names instead of filenames

Content Manager now shows Title and Summary columns from Kiwix metadata
instead of just raw filenames. Metadata is captured when files are
downloaded from Content Explorer and stored in a new zim_file_metadata
table. Existing files without metadata gracefully fall back to showing
the filename.

Changes:
- Add zim_file_metadata table and model for storing title, summary, author
- Update download flow to capture and store metadata from Kiwix library
- Update Content Manager UI to display Title and Summary columns
- Clean up metadata when ZIM files are deleted
