Realtime API: Support 'base_model' cost tracking + show response in spend logs (if enabled) (#9897)

* refactor(litellm_logging.py): refactor realtime cost tracking to use common code as rest

Ensures basic features like base model just work

* feat(realtime/): support 'base_model' cost tracking on realtime api

Fixes issue where base model was not working on realtime

* fix: fix ruff linting error

* test: fix test
