remove dead code across frontend and backend

- Remove TS ConfigurationManager class in configSchema.ts (called
  non-existent backend methods; only getDefaults() was used, replaced
  with direct import)
- Remove Python update_config method and create_config_from_args (unreachable
  since plugin.py routes through update_config_from_dict; also carried a
  duplicate @staticmethod that would crash at runtime)
- Delete configuration_helpers_generated.py entirely (all three functions
  were unused)
- Remove their generators from generate_python_boilerplate.py
- Remove dead generated code from config_schema_generated.py
  (create_config_dict, get_function_parameters, TOML_FIELDS, SCRIPT_FIELDS)
- Remove duplicate import in config_schema.py
- Remove unused config prop from UsageInstructions component
