fix(pilot): applied_at stamps on run-declaring actions, not Apply click

Per Phase 9 §5. Before: banner Apply click stamped applied_at
regardless of whether the engineer had committed to running anything,
starting the Verifying timer prematurely. After:

- handleApplyFix no longer calls applyFix(). It just routes to the
  right surface (TemplateMatchPanel / InlineNoTemplateDialog / Script
  Builder tab).
- handleScriptDecision stamps applied_at for one_off + draft_template
  (both labels are 'Run now, …' — the click is the declaration).
  build_template does not stamp.
- TemplateMatchPanel's new 'I ran this' button calls applyFix via a
  new onMarkRun prop.
- Script Builder tab Submit does not stamp (a draft is not a run).

No backend change — the /apply endpoint is unchanged. Only call sites
move.
