Fix database cleanup table configurations for Airflow 3

[Alwaysgaurav1]

Description

Updates table configurations in airflow.utils.db_cleanup to align with Airflow 3 database schema migrations and fixes test discovery:

1. task_reschedule:

   • In Airflow 3 (migration 0063), dag_id, task_id, run_id, map_index, and try_number were dropped from task_reschedule and replaced with ti_id foreign key referencing task_instance.id.
   • Removed obsolete dag_id_column_name="dag_id" which previously produced SQL errors (column base.dag_id does not exist) when running airflow db clean --dag-id.
   • Added "task_reschedule" to task_instance.dependent_tables so that dependent reschedules are cleaned prior to task instances.

2. asset_event:

   • Corrected dag_id_column_name from "dag_id" to "source_dag_id" to match the table schema.

3. callback & sla_miss:

   • Updated table name from callback_request to callback.
   • Removed obsolete sla_miss table (replaced with Deadlines in Airflow 3).

4. Test Suite Fixes:

   • Fixed test_no_models_missing in test_db_cleanup.py to dynamically locate airflow.models across monorepo packages.
   • Updated exclusion list to accurately account for all 52 Airflow 3 declarative models.
   • Added unit tests covering task_reschedule (recency and cascade), asset_event DAG ID filtering, and callback cleanup.

Testing

• Ran unit tests: uv run --project airflow-core pytest airflow-core/tests/unit/utils/test_db_cleanup.py (74 passed, 0 failed).
• Formatted and linted with ruff.
