Add actor/cast information with person pages and search support

Integrate TMDB credits data into the app: cast carousels on title detail
pages, person detail pages with biography and filmography, and person
search results in the command palette. Includes new persons/titleCast
DB tables, profile image caching, and a nightly credits refresh cron job.
