URL: https://github.com/apache/airflow/pull/63878
## Problem
`init_log_folder()` iterates through all parent directories from `/` calling
`mkdir()` on each. For paths on mounted filesystems (e.g.
`/mnt/nfs-share/airflow/logs`), this calls `mkdir('/mnt')` and
`mkdir('/mnt/nfs-share')` which fails with `PermissionError` because the
Airflow user cannot create system-level directories. `exist_ok=True` only
suppresses `FileExistsError`, not `PermissionError`, crashing all Airflow CLI
commands including `airflow db migrate`.
## Fix
- Replaced the explicit parent loop in `init_log_folder()` with
`Path.mkdir(parents=True, exist_ok=True)` which only creates directories that
don't already exist, stopping at the first existing parent
- Wrapped the call in `try/except (PermissionError, OSError)` to log a
warning instead of crashing
- Wrapped the `init_log_folder()` call in `configure_logging()` with the
same try/except so CLI commands continue even if the log folder cannot be
created
Fixes #63863
