feat(mana-web): keyboard shortcuts for workbench + nav bars

- 1–9 scroll to the Nth open app on the workbench homepage; 0 opens the
  app picker.
- q/w/e toggle the bottom bars (workbench tabs / search / tags); r opens
  the user-menu PillDropdownBar (expanding the PillNav first if needed);
  t toggles the PillNav visibility.

Adds a `data-user-menu-trigger` hook on the user pill so the layout can
drive the menu bar programmatically without duplicating its config.
