Closes #20834: Add support for enabling/disabling Tokens (#20864)

* feat(users): Add support for enabling/disabling Tokens

Introduce an `enabled` flag on the `Token` model to allow temporarily
revoking API tokens without deleting them. Update forms, serializers,
and views to expose the new field.
Enforce the `enabled` flag in token authentication.
Add model, API, and authentication tests for the new behavior.

Fixes #20834

* Fix authentication test
