Fix: Restore library stats functionality and remove debug logging

- Fix usePlexLibraries composable to return stats and details
  - Updated loadLibraries signature to match PlexSettings usage
  - Now accepts: sections, authToken, serverUrl, username, fetchFn
  - Returns: { stats, details } object instead of updating refs
  - Added watchtime calculation from Tautulli API

- Update processLibrarySection to work with passed parameters
  - Accept stats and details objects instead of using refs
  - Accept serverUrl and fetchLibraryDetailsFn as parameters
  - No longer depends on composable internal state

- Remove all debug console.log statements
  - Clean up usePlexAuth composable (removed 13 debug logs)
  - Clean up PlexSettings component (removed 9 debug logs)
  - Keep only error logging for troubleshooting

Library stats now display correctly after authentication ✓
Build size reduced by removing debug code
