✨ feat: add vibration feedback support for UI events

- Add genericVibration class with 5-second cooldown and 1-second pulse
- Integrate vibration triggers for new messages and contact discoveries
- Add conditional compilation support with PIN_VIBRATION guard
- Implement abstract interface for vibration in UITask system
