fix(user): restore organizations tab on user profile (#39577)

Fixes #39572

The shared user cards template calls the User-only `IsTypeBot` method.
The profile organizations tab passed `*organization.Organization` values
to that template, so `/{username}?tab=organizations` returned a 500
error.

Organizations are now converted to Users before rendering.
