Move cancel button into actionbar (#7297)

## Summary
Move the interrupt control into the actionbar so cancellation sits with
the run controls.

## Changes
- add a cancel button to the actionbar with the existing interrupt
tooltip and disabled state
- remove the cancel button and related execution wiring from the top
menu section to avoid duplication

## Review Focus
- spacing/hover states of the new cancel control in both docked and
floating modes

## Screenshots (if applicable)
- n/a

Tests: pnpm typecheck; pnpm lint:fix
