Logan CusanoandClaude Opus 5.5 e5fc6ca838 map: aircraft details dock at the right edge instead of a popup
The popup sat on top of the plane and hid the trail it had just drawn.
Details now render in a panel docked top-right (portaled into the
Leaflet container, click/scroll propagation disabled), so the map can
be panned to follow the path. Clicking empty map or the same plane
deselects; hover tooltip unchanged.

Verified: tsc --noEmit clean (node:20 on radio-box).
