fix(python-client): expose all configurable fields in update_bank_config()

Add 10 missing bank-configurable fields to update_bank_config():
- entity_labels, entities_allow_free_form
- consolidation_llm_batch_size, consolidation_source_facts_max_tokens,
  consolidation_source_facts_max_tokens_per_observation
- retain_default_strategy, retain_strategies
- reflect_source_facts_max_tokens
- mcp_enabled_tools
- llm_gemini_safety_settings

Previously these could only be set via raw PATCH to /config.
All new params are keyword-only with None defaults (backwards compatible).
