bug-report c25e9b55: long-press scene actions were in Polish — translate menu,
banner and confirm dialogs to English. Thumb 'error' state (e.g. expired sxyprn
thumbnail 404) now shows the same 🎬 placeholder as 'empty' instead of a ⚠ broken
glyph (bug 2026-06-10).

bug-report 5a6844db: the hold-to-preview animated gesture did nothing useful.
Replace it with a long-press action menu on scene tiles:
- Ukryj scenę → POST /scenes/{id}/hide
- Oznacz jako duplikat → enter selection mode; tapping another tile merges the
long-pressed scene INTO the tapped one (POST /scenes/{keep}/merge/{drop}).
SceneActionsProvider holds the selection state + a bottom banner, so it works across
all 5 scene-list screens via the shared SceneTile (no per-screen wiring). Selecting
mode highlights tappable tiles and badges the pending duplicate. Animated thumbnails
kept only as a still-fallback image; has_animated_thumbnail filter removed.
