Add Refresh Modules button to sidebar for hot-reloading modules

- Sidebar button at bottom re-scans modules/ directory on click
- POST /api/modules/reload endpoint returns updated counts and module list
- Button shows success/failure feedback, auto-reloads category pages
- Enables hot-dropping new modules without restarting the server
