Merge commit '1e3b19230a48174acf524cf1a9f5a498e220ea7d' into glitch-soc/merge-upstream

Conflicts:
- `app/models/account.rb`:
  Upstream added new validations close to lines on which glitch-soc had
  modified validations to handle custom limits set through environment
  variables.
  Ported upstream changes.
- `config/initializers/content_security_policy.rb`:
  Upstream added `AZURE_ALIAS_HOST`. Glitch-soc's version of the file is
  completely different.
  Added `AZURE_ALIAS_HOST` to our version of the file.
