feat(performer): replace dev Re-scrape button with top-tag chips

bug-report 1a4bf258: "Re-scrape mógłby zniknąć, za to tagi/kategorie by mogły".
Re-scrape was a dev-only bulk thumbnail/tag enrich — noise on the performer page
(per-scene enrich already happens on SceneDetail). Removed it; kept Search.

New GET /performers/{id}/tags aggregates scene_tags across the performer's
live-playback scenes (top N). PerformerScenes renders them as chips → tap navigates
to TagScenes. Search button widened to full row.
