fix: onboarding gamepad — autofocus, click sounds, focus styles

All screens:
- playNavSound('action') on every button click
- path-action-button orange focus glow (removed from suppression list)

Per-screen autofocus:
- Intro: CTA button (after animation)
- Path: Continue button
- Identity: name input
- Backup: passphrase input, Continue after download
- Verify: Sign Challenge, then Finish after verification
- Done: Set Password button
