WorldMapPanel owns the world state and applied the /api/jump response
locally, so MissionControl's lifted /api/system state (LOCAL SYSTEM tab,
CARGO HOLD, SECTOR row) stayed on the previous system until a full refresh.
The panel now takes an onJumped callback that MissionControl wires to an
/api/system refetch after every successful jump.
Remove the bottom JUMP ROUTES button list; systems adjacent to the current
one become clickable galactic-chart nodes (same POST /api/jump flow, same
state refreshes). Current + unreachable systems are dimmed and not
clickable. NodeGraph gains optional onNodeClick + per-node disabled
(backward-compatible); two smoke tests updated to click chart fields.
