AI Assistant 800c45916e feat(geoportal): rectangle + freehand polygon selection drawing on map
Rectangle mode (Dreptunghi):
- Mousedown starts drawing, mousemove shows amber overlay, mouseup selects
- All terenuri features in the drawn bbox are added to selection
- Map panning disabled during draw, re-enabled after
- Minimum 5px size to prevent accidental micro-selections

Freehand mode (Desen):
- Each click adds a point, polygon drawn with GeoJSON source
- Double-click closes polygon, selects features whose centroid is inside
- Ray-casting point-in-polygon algorithm for spatial filtering
- Double-click zoom disabled during freehand mode

Draw state clears when switching selection modes.
