Web Dashboard Version 2.1.2

This is a minor bug-fix release:

• Show the correct Closed On and Assigned On dates in reports.
• Show a Resolution input on new and edited activities that are configured to have one.
• Fix our usage of @turf/center-of-mass for polyline selections — important for activities with a linear shape like Access Roads.

These changes are built on other recent versions 2.1.0 and 2.1.1.
