TV Shows previously depended on TMDB metadata or a small built-in list. Add a default Latest Library feed from the provider on desktop and TV, with pagination, duplicate suppression, retry after an outage, and preservation of already loaded titles.

Without a TMDB key, search covers loaded provider shows and built-in titles and says so in the interface. Repeating a search after loading another page recomputes results instead of reusing a cached miss. Configured-key search continues to use TMDB. Samsung's manifest permits the exact provider catalog origin.

This PR addresses the TV Shows portion of HBR-002. Anime classification and catalog coverage remain a separate follow-up; animation alone is not classified as Anime. Provider listing does not guarantee playback availability.

Validation:

• Independent review and subsequent re-review: no remaining findings.
• Consumer, player, TV smoke, and TV staging checks passed.
• Production renderer/preload/main IPC smoke passed in both no-key and configured-key modes using isolated fixtures. It exercises pagination, duplicate rows, an outage and retry, and search after an earlier miss; the configured-key mode uses a fake test key, with no production configuration or secrets changed.
• Combined Windows 2.3.6 packaged-app smoke passed, including both Shows key modes, using isolated temporary profiles. This combined QA build also included separately scoped playback/server work; those changes and version bump are excluded from this PR.

No installer, staged TV output, local queue, profile, or dependency artifacts are included.
