AppFlow operators validate template fields in constructors, so Jinja expressions are rejected before Airflow can render them. Move those checks to execution time so Dags can use templates while keeping the same runtime validation.

AppFlow operators validated templated fields in their constructors, which rejected Jinja expressions before Airflow could render them.
This moves the AppFlow source and filter-date validation to execution time so templates are rendered before validation runs. The AppflowBaseOperator exemption is removed from the operator constructor validation list.
