fix(ui): pin compact task-suggestion split button to the card top-right (#121246)

- Uses a four-column grid with inline top-row actions to keep the compact control pinned to the card corner.
- Fixes both split halves at 26px, eliminating the chevron overhang.

Release-note context: the suggested-task card's action button is now a compact split control in the top-right corner, matching the intended design.
