fix: restore Verify button fallback with honest labeling

Re-add the onVerify fallback for in_progress/pipeline features without context,
but fix the misleading UX issue where the button said 'Resume' but executed
verification (tests/build).

Changes:
- Restore onVerify fallback as 3rd option after skipTests Verify and Resume
- Change button label from 'Resume' to 'Verify' (honest!)
- Change icon from PlayCircle to CheckCircle2 (matches action)
- Keep same green styling for consistency

This makes sense because if a feature is in_progress but has no context,
it likely completed execution but the context was deleted. User should be
able to verify it (run tests/build) rather than having no action available.
