refactor(dashboard): shared LoggedTag component, fix dead toggle and colliding a11y labels

- Create shared LoggedTag component to prevent style drift across three render paths
- Replace all three inline spans with single LoggedTag component import
- Fix dead "Show technical detail" toggle: only render when card has git commits
- Fix colliding screen-reader labels in unassigned tray by using commit subject instead of generic text
- Ensures manual entries stay visually consistent and semantically correct everywhere
