beacon: add unlock notification toasts for new buildings and projects

Players now get animated toast notifications (top-right) when:
- A new building becomes available to buy
- A new research project becomes available

Toasts are color-coded: blue for buildings, gold for projects.
Seen state is tracked and persisted in saves so toasts don't repeat.

This was the biggest UX gap in the game -- without notifications,
players had to manually scan the building/project lists to notice
new unlocks. Critical for idle games where pacing matters.
