Matches:
- Outcomes are now per-match (<match>_<fighter>_<outcome>), generated for each
  match's two fighters, so each match's outcome scenes are its own/different.
- Support multiple matches for the same pair+environment via unique match names
  (numeric suffix); scanner and delete isolate siblings correctly.
- List view shows a lightweight preview (clip00 keyframe or metadata poster);
  detail view shows clips AND the match's outcomes per fighter, each with an
  editable prompt + re-render + remove. Clip/outcome prompts save to
  prompts.json. Legacy per-fighter outputs still listed.

Prompts page: reframed as master prompts that auto-write a unique prompt per
clip/outcome of every match; static templates marked fallback-only.

Terminal: per-card action jobs (regenerate, train LoRA, match render) now echo
their progress to the terminal too.
