fix: check if user is blocked on profile popup

This PR is a response to @emizzle's suggested change in PR #1431 . It checks if a user is blocked before exposing certain functionality to the user in a Profile popup. The new unblock button also has a fail-safe unblock confirmation popup

disable the chat input if 1-on-1 chat recipient has been blocked.
