a11y/ux: modals close on Escape (0.75.0)

- the agent ClassModal and the booth 'instance created' modal could only be
  dismissed by clicking the backdrop or the X — no Escape, a standard
  keyboard/UX expectation
- add a keydown(Escape) -> close to both (ClassModal listens while mounted;
  the booth modal attaches the listener only while newInst is set)
- verified live: agent modal opens then closes on Escape
