stellarshenson 96f3d546b0 fix: protect jupyterhub_config.py from import errors ...

Fixed NameError when custom_handlers.py imports from jupyterhub_config.py
by protecting all c.* assignments with 'if c is not None:' checks.

Changes:
- Wrapped c = get_config() in try-except to handle module import context
- Defined DOCKER_SPAWNER_VOLUMES as module-level constant
- Modified get_user_volume_suffixes() to accept volumes dict parameter
- USER_VOLUME_SUFFIXES calculated from constant (importable without c defined)
- Protected all c.* configuration assignments with 'if c is not None:' guards

This allows custom_handlers.py to import USER_VOLUME_SUFFIXES without
triggering "NameError: name 'get_config' is not defined" when the config
file is imported as a module rather than loaded by JupyterHub.

Volume management now works correctly - configuration can be safely imported
by handlers to validate volume names against USER_VOLUME_SUFFIXES.
