Subject: [PATCH] fix(frontend): passing the MCP header and env setting to
 backend (#810)

This pull request adds support for custom HTTP headers to the MCP server configuration and ensures that these headers are properly validated and included when adding new MCP servers. The changes are primarily focused on extending the schema and data handling for MCP server metadata.
