fix: kiosk cursor, Esc dead-end, PWA prompt, password overlay, gamepad Enter

- Kiosk: show cursor when active (removed -nocursor from Xorg),
  unclutter hides after 3s idle. X11 on VT7 for Ctrl+Alt+F1/F7 switching.
- Kiosk: keep getty@tty1 running so MOTD is accessible via Ctrl+Alt+F1
- Kiosk: disable Chromium password save overlay (--password-store=basic)
- Esc: don't navigate back from top-level pages (dashboard, login, kiosk)
  to prevent dead-end at root redirect
- PWA: suppress install prompt in kiosk mode (/kiosk path)
- Gamepad: Enter in text fields moves focus to next element (submit button)
  instead of submitting the form
