Fix Bluesky authentication to load credentials from config.yaml

- Update default_login() to use get_bluesky_config() instead of os.getenv()
- Update init_client() to load PDS_URI from config with fallback to env var
- Update all PDS_URI references to use config loader
- Remove username/password printouts for security
