Find and reset users with mismatched usernames and profiles

Users that have updated their username can get their account into a bad state (most recently trust bonus tabs do not appear for these users and they cannot manage their trust bonus / submit passport)

We need to find mismatched users and re-map their user and profile: https://discord.com/channels/562828676480237578/1017330730143072316

Start by reviewing the linked Discord discussion to understand how mismatched users and profiles are identified. Locate the user/profile mapping and determine how the affected records can be remapped safely. Done means mismatched accounts are corrected and users can manage trust bonus and submit a passport again.
