Add context menu actions to hide/show all geometry for well visibility

Two new actions added to the well path context menu:
- "Hide All Geometry (Show Wells)": hides grid cells, faults, and intersections,
  then forces simulation wells and well paths visible.
- "Show All Geometry": restores grid cells, faults, and intersections visibility.

Added RimIntersectionCollection::setActive() for direct state control.
