feat(dashboard): zoom + pan on the world map - #7
Merged
Conversation
Closes #3. The dashboard world map content is wrapped in a ZoomableGroup so it supports wheel-zoom and drag-to-pan, plus a top-right control cluster (zoom in / out / reset). Zoom/center is controlled state shared by the gestures and the buttons. Markers counter-scale by 1/zoom so they stay a constant screen size, and the tooltip is hidden while dragging.
