CRM457-2221: Allow providers to generate filtered lists

[patrick-laa]

Description of change

• Providers can access the search endpoint
• The search endpoint allows passing in multiple office codes
• Searches can be sorted by UFN
• Searches can be sorted by the date of the most recent state change (e.g. for submitted applications it's when they were submitted, not the date of the most recent caseworker assignment)
• Caseworker app can no longer subscribe/unsubscribe (since it doesn't do that any more)

Link to relevant ticket

[elken]

Doesn't directly relate to this ticket but having these fields in the common gem will help us with the future query param validation ticket, agreed?

[patrick-laa]

Agreed. I think there's a question of how much search-related stuff goes into the common gem, because a lot of this stuff knows to a certain extent about the structure of the NSM and PA payloads, but trying to move e.g. view definitions into the gem is gonna send us loopy...
