Implement "Leave Community" Feature

[dillchen]

Description

Currently, users can join communities but lack a straightforward way to leave them. This ticket adds a "Leave Community" feature that removes users from communities they no longer wish to be part of. The implementation should ensure all relevant data associations are properly updated when a user leaves a community.

Acceptance Criteria

• Users can leave a community via a clearly visible UI action
• Users are properly removed from the community's member list
• Users lose any community-specific roles/permissions upon leaving
• Users receive confirmation when they successfully leave a community
• The UI updates immediately to reflect the changed membership status
• Users can rejoin a community after leaving if they choose to

Implementation Plan

• Platform: DeleteAddress -> DeleteAddresses
  -- Update the route to delete subscriptions + downgrade roles of the soft-deleted addresses (just in case)
• Client: Allow user to Leave Community from the sidebar (Join Community button will become Leave Community)

Technical Notes

• Use a database transaction to ensure all related operations complete successfully
• The feature may affect community statistics and member counts
• Consider performance impacts for large communities
• Ensure proper error handling and recovery
• Document the feature for both users and developers

@Rotorsoft / @timolegros anything that we missed from the platform side that this ticket did not cover?

Is the expectation for the new route that we remove all of a user's addresses from a community because we already have DeleteAddress.command which basically does "leave community" if you only have a single address left in that community?

Potential platform changes could be simply:

• DeleteAddress -> DeleteAddresses
• Update the route to delete subscriptions + downgrade roles of the soft-deleted addresses (just in case)

Yea we should do that:

Going to update the scope of this:

• Platform: DeleteAddress -> DeleteAddresses
  -- Update the route to delete subscriptions + downgrade roles of the soft-deleted addresses (just in case)
• Client: Allow user to Leave Community from the sidebar (Join Community button will become Leave Community)

Turns out we already have DeleteAllAddresses which was added when the address management in edit profile was refactored. Only change required on platform is updating the side effects (subscriptions).
