refactor: update forward authentication handling in domain schema and tests

- Replaced `forwardAuthProviderId` with `forwardAuthEnabled` in the domain schema to simplify the configuration of forward authentication.
- Updated related tests to reflect this change, ensuring consistency across the application.
- Introduced a new SQL migration to create the `forward_auth_settings` table for managing authentication domains and their configurations.

This refactor enhances the clarity and maintainability of the forward authentication logic within the application.
