feat: add pagination to dashboard and fix mjs mime type

- Implemented client-side pagination in `dashboard/index.html` (20 items per page).
- Added pagination controls and CSS utilities in `dashboard/styles.css`.
- Fixed `src/dashboard.mjs` to serve `.mjs` files with `text/javascript` MIME type.
- Verified `npx torch-lock init` functionality (no changes needed to landing page).
