📚 docs: Update Preset Fields and Query Params (#361)

* 📘 docs: Enhance Model Specs documentation with new parameters and default values

- Updated Model Specs documentation to include new parameters: `reasoning_effort`, `reasoning_summary`, `useResponsesApi`, `web_search`, `disableStreaming`, `thinking`, and `thinkingBudget`.
- Added some default values for existing parameters
- Documented changes in changelog

* docs: change note on model params from 'numbers' to 'values' to account for new params that don't have numeric values

 - Added user placeholder variables support to Custom Endpoint Headers:
   - Users can now use `{{LIBRECHAT_USER_ID}}`, `{{LIBRECHAT_USER_EMAIL}}`, and other user field placeholders in custom endpoint headers
   - See: [Custom Endpoint Object Structure - Headers](/docs/configuration/librechat_yaml/object_structure/custom_endpoint#headers) for details
+- Improved [Model Specs documentation](/docs/configuration/librechat_yaml/object_structure/model_specs) with parameter support updates (disableStreaming, thinking, thinkingBudget, web_search, etc...)
