feat(ui): add slide animations and stack reflow

- Add animation module with state machine (Appearing, Visible, Reflowing, Disappearing, Hidden)
- Slide-in animation when notifications appear
- Slide-out animation when notifications close
- Stack reflow: remaining notifications animate up when one closes
- Configurable animation duration and slide direction
