🧠 fix: Agent Title Config & Resource Handling (#8028)

* 🔧 fix: enhance client options handling in AgentClient and set default recursion limit

- Updated the recursion limit to default to 25 if not specified in agentsEConfig.
- Enhanced client options in AgentClient to include model parameters such as apiKey and anthropicApiUrl from agentModelParams.
- Updated requestOptions in the anthropic endpoint to use reverseProxyUrl as anthropicApiUrl.

* Enhance LLM configuration tests with edge case handling

* chore add return type annotation for getCustomEndpointConfig function

* fix: update modelOptions handling to use optional chaining and default to empty object in multiple endpoint initializations

* chore: update @librechat/agents to version 2.4.42

* refactor: streamline agent endpoint configuration and enhance client options handling for title generations

- Introduced a new `getProviderConfig` function to centralize provider configuration logic.
- Updated `AgentClient` to utilize the new provider configuration, improving clarity and maintainability.
- Removed redundant code related to endpoint initialization and model parameter handling.
- Enhanced error logging for missing endpoint configurations.

* fix: add abort handling for image generation and editing in OpenAIImageTools

* ci: enhance getLLMConfig tests to verify fetchOptions and dispatcher properties

* fix: use optional chaining for endpointOption properties in getOptions

* fix: increase title generation timeout from 25s to 45s, pass `endpointOption` to `getOptions`

* fix: update file filtering logic in getToolFilesByIds to ensure text field is properly checked

* fix: add error handling for empty OCR results in uploadMistralOCR and uploadAzureMistralOCR

* fix: enhance error handling in file upload to include 'No OCR result' message

* chore: update error messages in uploadMistralOCR and uploadAzureMistralOCR

* fix: enhance filtering logic in getToolFilesByIds to include context checks for OCR resources to only include files directly attached to agent
