feat(ui): booster bar targeting in the game screen

Mount BoosterBar below the tray (only while playing), guarded so legacy GameScreen tests without a SaveRepository keep passing. Tapping a booster arms targeting: shuffle applies immediately; hammer/line-bomb arm a board tap (hammer clears a cell, line-bomb opens a row/column chooser). An empty booster opens a get-one dialog (ad grant lands in Task 15). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

+// Widget tests for the booster bar mounted in the game screen.
+//
+// Board-geometry taps (hammer / line-bomb cell selection) are NOT covered here:
+// the board is laid out inside an Expanded/Center whose pixel geometry is not
+// deterministic in a widget test, so a pixel-accurate cell tap is unreliable.
+// Those paths are left to manual QA (see the agent report). What we CAN verify
+// deterministically is the inventory side-effect: shuffle applies immediately
+// and spends one booster.
