Paint canvas: mouse moves are no longer dropped while the pointer keeps moving
Paint canvas: mouse moves are no longer dropped while the pointer keeps moving `PaintSurface`'s mousemove throttle set `mouseMoveThrottle.current` only when it **dropped** an event, never when it handled one. When events arrive faster than the 60 Hz interval (high-refresh displays, fast mice), each event lands within 16 ms of the previous dropped one, so every event gets dropped. The brush cursor, shape preview and hover state then freeze until the pointer pauses. The fix records the timestamp when an event is handled, so the throttle lets through one event every ~16 ms as intended. It's a 2-line change in `PaintSurface.tsx`.
