feat(FN-2466): prefer workflow lookup names in progress labels

- Thread workflow name lookup data from Board into Column, TaskCard, and WorktreeGroup components
- Update unified task progress resolution to prefer workflow lookup names over raw workflow IDs
- Keep fallback behavior for missing lookup entries so progress labels remain stable
- Expand Board, Column, and TaskCard tests to cover lookup-based workflow name rendering
