Just change all imports and dependencies.

We still need to force the v3 format internally because i18next-scanner
doesn't support the new format and v4 drops support for Safari<13.

By setting compatibilityJSON things should continue to work as before.

No longer needs babel, but requries an alpha version of the typescript plugin
for eslint 8 support

We now enable it by default for everyone. The plan is to load the API
user instead and not the person as a next step. This api should work
even for users that don't have a person associated.

This removes the 'show-image' (false by default) and removes the functionality
to show a user profile image in the logout dropdown.

We've never used this actively and want to clean things up, so remove it.
