- Channel-row tags show only what's attached; a '+' opens a per-channel picker. Clicking a tag
filters the feed by it; a 'Your tags' sidebar widget makes that filter visible/clearable.
- Tag manager dialog (add/rename/delete; delete only confirms when the tag is in use), reachable
from the Channel manager and the feed sidebar; hovering a tag's count lists its channels, each a
link that focuses it in the Channel manager (DataTable gains an external filter input).
- Video cards get a reset action that clears all watch state (incl. an in-progress position).
- api.req() now raises the error dialog on 5xx and 400/409/422 with the server's reason.
Live streams and upcoming/premiere videos have no fixed duration, so the
playlist row and video card left a blank where the runtime usually sits.
Show a LIVE (red) or upcoming badge instead, so it's clear the missing
time is by design, not a sync gap.
Feed, VideoCard, Sidebar, PlayerModal, Channels, Stats, SettingsPanel,
OnboardingWizard, NotificationCenter, Toaster, ErrorBoundary and the relativeTime
helper are now fully translated in Hungarian, English and German, each with its own
locale area file (auto-loaded). Key parity verified across all three languages.
