fix(accounts): align action column with table edge

Let the final account action column absorb the table's remaining width instead of translating a fixed-width cell by a guessed offset. This keeps the Action header and row menus centered together at the visible right side across window widths and removes the ineffective fixed transform. Add focused regression coverage for the flexible final grid track.
