fix(FN-2714): restore task timer chip to footer metadata row

- Move TaskCard time indicator rendering from the header back into the footer metadata row
- Render timer and files-changed metadata together in the shared footer row layout
- Update timer chip CSS to stay right-aligned with margin-left:auto and prevent shrinking
- Update TaskCard and mobile board tests to assert footer placement and alignment behavior
