simplify: remove Space key, use P/Shift+P for audio playback

- Remove Space key handler from handleShortcutKey
  Space is not needed - use P/Shift+P instead

- Clarify hotkeys help text
  p/п = play front audio
  P/П = play back audio (bg-bg only)

The SetOnTypedRune handler already correctly handles case-sensitive
keys (p vs P, a vs A) for both playback and regeneration.
