feat(stalker): full Live TV channel list for complete search, count badges, and all-channels grid (#1209)

Load the complete ITV channel list once per portal (Ministra get_all_channels with a paged crawl fallback) and use it for: full local search across every channel, per-genre category count badges, an all-channels paginated grid on Live TV entry, and eager bulk EPG so row previews appear without playing a channel. Censored (adult) genres absent from get_all_channels fall back to the legacy paged flow and show no badge. Includes mock-server support, unit + E2E coverage, and architecture docs.
