Closes #2885

Changes

• Enumerates all possible values of filterBy when updating search params to match value on archived item list
• Adds a new isNotEqual wrapper that inverts lodash's isEqual for use in the hasChanged option of @property/@state decorator functions
  • Applies these wherever relevant, both within and outside of filters
• Updates how maps are updated in checkbox filters
  • Previously they were updated by updating the value of the old map, and then creating a new map with the updated old map as an initial value. While this works fine for the default comparator which compares values by reference, because every updated causes the map to be recreated we need to compare values of the map by value instead, which meant that because the old value was updated before creating the new map, the old and new map would have the same contents when compared.
  • The solution here is to create a new map by using the existing value of the old map plus the update as a key-value tuple as the initial value. This way the old value isn't updated, so the by-value comparison works as expected.

Testing

• On both the workflows and archived items list pages, test that all of the filter chips work as expected.
  • In particular, test that checkbox-type filters update the state of the filter chips as well as the URLs when clicked, and that they don't hang your browser
• On the archived items list page, test that you can enter a search term, and then clear that term, and that the URL updates to reflect both changes.

Known issues

The search box on the workflows list page is not yet hooked up to persist its value via URL. That's coming soon!
