Add comprehensive tests for STI VideoLibrary implementation

- Add model specs for .tutorials, .podcasts, .intros scopes
- Add request specs for tutorials#index (Tutorial type only) and tutorials#video_library (all types)
- Add routing specs for /video_library route
- Add home video library controller specs:
  - All content types displayed with youtube_url
  - Excludes records without youtube_url
  - Correct ordering by position then created_at
