beacon: add progression toast notifications for phase/building/project unlocks

Animated toasts slide in from the right when:
- A new phase is reached (gold border)
- A building unlocks for the first time (blue border)
- A research project completes (green border, gold title for milestones)

Toasts auto-dismiss after 4s with fade-out. Max 4 visible at once.
seenBuildings state persisted in save data so toasts don't re-fire on reload.

This makes progression events impossible to miss — previously they only
showed in the scrolling system log.
