fix(ci): add missing provider docs, fix deprecated model refs in cost tests

- Add black_forest_labs and charity_engine to provider_endpoints_support.json
  (fixes check_code_and_doc_quality job)
- Replace o1-mini with o1 in test_reasoning_tokens_no_price_set (model removed
  from cost map)
- Replace gemini-2.5-pro-exp-03-25 with gemini-2.5-pro in
  test_generic_cost_per_token_above_200k_tokens (model removed from cost map)
- Fix test_get_cost_for_anthropic_web_search to use claude-3-7-sonnet-20250219
  with custom_llm_provider='anthropic' so web search cost is computed correctly
