feat(users): import Plex Home profiles from the admin UI

[0xSysR3ll]

Description

#1594 ended up being a bit too large to review comfortably, so it has been split into three smaller, more focused PRs.
This is the third and final PR in the stack. It builds on the auth layer and adds admin import for Plex Home profiles.

• Fixes Add plex home linking #1402
• Closes feat(auth): support Plex home profile login #1594

The i18n check failed because translation messages are out of sync.

This usually happens when you've added or modified translation strings in your code but haven't updated the translation file.

Please run pnpm i18n:extract and commit the changes.
