Improve tray initialization and logging (#2048)

- Remove all async click handlers as the typing of the expected method
  is that of `void` so it doesn't know how to handle `Promise<void>`

- Replace the above with promise chains with correctly handle any errors
  by logging them

- Fix the tray menu update logic to actually produce a new menu when the
  reaction is run

- Improve the Clusters submenu generation to involve less work and to
  utilize the built-in checkmark rendering
