### Apache Airflow version
main (development)
### If "Other Airflow 2/3 version" selected, which one?
_No response_
### What happened?
After updating to a build of Airflow that includes PR #57815, the FAB auth
manager endpoint `/auth/token` started failing with a 500 error and the
following exception in the API server logs:
```
RuntimeError: Working outside of application context.
...
File ".../airflow/providers/fab/auth_manager/security_manager/override.py",
line XXX, in auth_type
return current_app.config["AUTH_TYPE"]
```
The call stack shows this originates from
`FABAuthManagerLogin.create_token(...)`, which reads
`auth_manager.security_manager.auth_type`, and that `auth_type` property is
implemented as `return current_app.config["AUTH_TYPE"]` in
`FabAirflowSecurityManagerOverride`.
In PR #57815, the FastAPI routes in
`providers/fab/src/airflow/providers/fab/auth_manager/api_fastapi/routes/login.py`
were changed: the `create_token`, `create_token_cli`, and `logout` endpoints
no longer wrap their logic in with `get_application_builder(): ...`. Instead,
they now call `FABAuthManagerLogin.create_token(...)` (or
`get_auth_manager().get_url_login()`) directly, without setting up a Flask app
context.
As a result, when these endpoints are hit via the API server, `current_app`
is not bound and any access to `current_app.config["AUTH_TYPE"]` (and similar
properties) fails with `RuntimeError: Working outside of application context.`
### What you think should happen instead?
