beacon: add buy mode toggle (x1/x10/MAX) with B keyboard shortcut

The game had buyMode logic (1, 10, -1 for max) but zero UI to switch
between them. Players could only buy one building at a time.

Changes:
- Added x1/x10/MAX toggle buttons above the BUILDINGS section
- Active mode highlights in gold
- Press B to cycle through modes
- buyMode persists across saves
- Init log mentions the B shortcut
