- The doctor commands to check the validity of existing usernames and
email addresses depend on functionality that have configurable behavior
depending on the values of the `[service]` settings, so load them when
running the doctor command.
- Resolves#6664
- No unit test due to the architecture of doctor commands.
# Testing
1. Set `[service].ALLOW_DOTS_IN_USERNAMES = true`.
2. Create a user that contains a dot in their username.
3. Run the `check-user-name` doctor command and verify there's no error reported.
