beacon: add click combo system with floating damage numbers

Active play now rewards consecutive clicks: each click within 2s of
the last builds a combo multiplier up to 5x. The WRITE CODE button
flashes on click and a floating number shows the amount gained,
turning gold at high combo. Phase progression also adds base click
power (+2 per phase). Combo decays with a visible progress bar.

Makes clicking relevant at every stage of the game, not just the
first 30 seconds.
