Mirror the JinaReranker pattern by accepting an optional `apiUrl` in the CohereReranker constructor (with COHERE_API_URL env-var fallback) and propagating `cohereApiUrl` through `createReranker` and the `createSearchTool` config. Defaults to https://api.cohere.com/v2/rerank, fully backwards compatible. Enables Azure AI Foundry serverless Cohere endpoints and other Cohere-compatible deployments.

Summary
Fix for danny-avila/LibreChat#12328
This PR adds support for configurable API URLs in the Cohere reranker, enabling users to specify custom endpoints (e.g., for Azure deployments) while maintaining backward compatibility with the default Cohere API endpoint.

The API URL resolution follows a priority order: explicit parameter > environment variable > default URL. This pattern matches the existing implementation for JinaReranker and provides flexibility for different deployment scenarios while maintaining sensible defaults.
