Fix domain hiding logic (#7765)

* Send rejections to followers when user hides domain they're on

* Use account domain blocks for "authorized followers" action

Replace soft-blocking (block & unblock) behaviour with follow rejection

* Split sync and async work of account domain blocking

Do not create domain block when removing followers by domain, that
is probably unexpected from the user's perspective.

* Adjust confirmation message for domain block

* yarn manage:translations
