Add settings to disable torrents and auto-extract

[caprado]

Summary

• Disable Torrents setting — hides all torrent-based download links (e.g. MiNERVA), useful for users in countries where torrenting carries legal risk
• Disable Auto-Extract setting — keeps downloaded zip/7z archives as-is without extracting, saving storage for emulators that can launch compressed files directly
• Direct/Torrent badge on download link cards so users can see the download method at a glance

Closes #13

Test plan

• Toggle "Disable Torrents" in Settings — torrent links should disappear from ROM detail pages
• Toggle "Disable Auto-Extract" in Settings — downloaded zip/7z files should remain compressed
• Verify Direct (green) and Torrent (orange) badges appear on download link cards
