fix(modtools): tame ModGroupMap scroll-wheel zoom (match PostMap)

The ModTools slash map (ModGroupMap.vue) used Leaflet's default scroll-wheel
zoom with no tuning. On modern mice/trackpads the sigmoid in _performZoom
saturates at ±4 zoom levels per wheel event, so tiny wheel nudges produced
enormous jumps.

PostMap.vue already sidesteps this by disabling scrollWheelZoom and enabling
the gestureHandling plugin (ctrl/cmd+scroll to zoom). Apply the same pattern
here: import gesture-handling CSS, register the handler on client, and set
mapOptions to match PostMap.

Preserve the existing map-lock behaviour in selectLocation() by explicitly
re-disabling dragging + scrollWheelZoom after the handler-disable loop —
otherwise gestureHandling.removeHooks() re-enables them via
_enableInteractions.
