Fix: Correct props passed to PlexLibraryStats component

PlexLibraryStats expects individual number props:
- movies: number
- shows: number
- music: number
- watchtime: number
- loading?: boolean

PlexSettings was incorrectly passing:
- :stats="libraryStats" (single object)

Fixed to destructure and pass individual props:
- :movies="libraryStats.movies"
- :shows="libraryStats.shows"
- :music="libraryStats.music"
- :watchtime="libraryStats.watchtime"

Library stats now display correctly ✓
