Surface live YouTube search in the existing feed, triggered explicitly so the
expensive API call is never per-keystroke.
- Header: the search box still filters the local catalog as you type; Enter or a
YouTube button escalates the term to a live search (hidden for the demo account).
- Feed: a dedicated infinite query renders results in the same VirtualFeed cards +
in-app player, under a banner with a back button and a quota note. No auto-paginate
(each page spends 100 units) — an explicit 'Load more (uses quota)' button instead;
quota/limit errors (incl. 429) shown inline. The empty local feed offers a
'Search YouTube for <q>' CTA.
- Library: a 'Search-discovered' toggle reveals search-ingested videos (hidden by
default); sent as exclude_search_discovered.
- Admin: search_daily_limit_per_user config field; new videos_search quota label.
- All new strings translated in HU/EN/DE.
The quota-attribution action keys were inconsistent (mixed verbs, ad-hoc names,
English-only labels). Introduce a QuotaAction constants holder (one source of
truth), rename every attribution call site to it, and add migration 0020 to
rename historical quota_events.action values. The display label now resolves
from i18n (quotaActions.<key>, EN/HU/DE) instead of a hard-coded English map.
Scheduler job ids and progress phase labels are a separate namespace and are
left untouched.
