fix(location): map drag interception + wrap precision chips

- The interactive picker map didn't tell ancestor views to stop intercepting
  touches, so a horizontal drag on the Teleport map got stolen (opening the nav
  drawer) instead of panning. Add the same requestDisallowInterceptTouchEvent
  touch listener LocationPreviewMap already uses.
- The precision chips were a single horizontally-scrolling Row; make them a
  FlowRow so "Region · ~1250 km … Building · ~38 m" wraps onto multiple lines.
