refactor(proxy): move config-callback registration to public util wrapper

Browse source 
The helper reached into litellm_logging private APIs; the repo's pyright
config has enableTypeIgnoreComments disabled and a strict per-rule budget,
so each new private import and call site counts against the gate. Move the
instance-registration-with-fallback logic behind a public
register_config_custom_logger_callback in litellm.utils, and let the
existing _add_custom_logger_callback_to_specific_event carry the fallback
(its else branch now registers the string when the custom-logger class
cannot initialize). Net change in private API surface: zero.
