fix(astrolabe): Fix NcSelect options and CSS loading

- Use :input-label prop for NcSelect field labels instead of :label
  (the :label prop sets the option label property key, not the visible label)
- Fix CSS loading in admin.php and personal.php templates to use
  astrolabe-main (the bundled CSS file)
- Update minimum Nextcloud version to 31 (required for Vue 3)
