Display a warning when an unverified user's identity changes (#28211)
* display a warning when an unverified user's identity changes * use Compound and make comments into doc comments * refactor to use functional component * split into multiple hooks * apply minor changes from review * use Crypto API to determine if room is encrypted * apply changes from review * change initialisation status to a tri-state rather than a boolean * fix more race conditions, and apply changes from review * apply changes from review and switch to using counter for detecting races * Remove outdated comment Co-authored-by: Richard van der Hoff <1389908+richvdh@users.noreply.github.com> * fix test --------- Co-authored-by: Richard van der Hoff <1389908+richvdh@users.noreply.github.com>
