Enable/disable mods, batch toggle & delete

- Add  column to mods table (auto-migrated)
- Toggle endpoint: rename .jar ↔ .jar.disabled on disk, flip DB flag
- Batch toggle & delete with checkboxes + JS helper (fixes nested-form bug)
- Raw Vec<(String,String)> form deserialization fixes 'duplicate field' error
- Batch action bars at top and bottom of mod list
- Uploads default to enabled=1, rescan skips .jar.disabled files
