fix(android): map pans after long-press instead of staying fixed like on iOS

[mariusud]

Description

On iOS, long-pressing an item on the map and dragging keeps the map fixed. On android the gesture is allowed through and the map pans instead.

As discussed in #3981.

This PR brings android to feature parity with iOS by consuming the move gesture after a long-press.
To test:

• Long-press a feature on the map
• Without lifting your finger, drag — the map should stay fixed and the feature should follow your finger
• This already works on iOS - android should now behave the same way

Thanks for working on this! The main issue is that mAfterLongPress is set on every long press (including empty map space), which will block panning after any long press — not just on features/markers. Also onMoveBegin isn't guarded so mapGestureBegin still fires, but onMoveEnd returns early skipping mapGestureEnd, which can leave isGestureActive stuck at true.
