The Flight Plan modal can be dragged (title bar, persisted as navaid.fpPos) but not resized — long routes need a taller window, and the fixed 92vw/84vh caps can't be tuned.
Add a bottom-right corner grip to resize the plan window. Persist the chosen size (navaid.fpSize) and restore it on reopen. Reuse the .resize-handle.corner-se styling already designed for the pinned-plan box in #338.
