feat(search): Library provenance filter (organic / all / search-only)

Replace the binary 'show search-discovered' toggle with a 3-way Source selector in the
Library toolbar, so users can also see ONLY search-discovered videos — not just hide or
mix them. Backend: feed param library_source = organic (default, hides via_search) | all
(both) | search (only via_search), applied in scope=all. Strings in HU/EN/DE.
