feat(ui): floating pulse hint for booster targeting

Replaces the plain bottom SnackBar with a BoosterHint pill that floats in the empty space above the board: season-accent coloured, a breathing glow that pulses only while armed (idle otherwise — no wasted ticker), slides/ fades in, shows the booster icon + prompt, and cancels on tap. 3 widget tests; full suite 234 green.
