Fixes: #67813
The scheduler orphaned-task adoption path loaded task instances with a
narrow `load_only(...)` set and then called `repr(ti)` while building the reset
log message. `TaskInstance.__repr__` reads `map_index` and `state`, so detached
instances with deferred columns could raise `DetachedInstanceError` and
crash the scheduler on restart.
This updates the scheduler query to load the fields needed by `repr(ti)` and
makes `TaskInstance.__repr__` defensive for detached/deleted ORM instances used
in logging.
Tests:
- `uv run --project airflow-core pytest
airflow-core/tests/unit/models/test_taskinstance.py::test_task_instance_repr_does_not_raise_for_deferred_columns
airflow-core/tests/unit/jobs/test_scheduler_job.py::TestSchedulerJob::test_adopt_or_reset_orphaned_tasks_loads_state_for_reset_logging
