fix(login v1): ensure the user's organization is always set into the token context (#10221)

# Which Problems Are Solved

Customers reported, that if the session / access token in Console
expired and they re-authenticated, the user list would be empty.
While reproducing the issue, we discovered that the necessary
organization information, would be missing in the access token, since
this would already be missing in the OIDC session creation when using an
id_token_hint.

# How the Problems Are Solved

- Ensure the user's organization is set in the login v1 auth request.
This is used to create the OIDC and token information.
 
# Additional Changes

None

# Additional Context

- reported by customers
- requires backport to v3.x
