📄 Description

Description:
Adds defensive checks to prevent the frontend from crashing when an invalid or non-OpenAPI spec is configured for External Tool connections.
Changes:

Guard against undefined paths in convertOpenApiToToolPayload to prevent Object.entries crash
Detect MCP-style configs used for OpenAPI connections and return a helpful error message instead of breaking the UI
This fixes the infinite loading screen that occurred when users accidentally configured an MCP server using the OpenAPI connection type.
Fixes [PR #198] [MERGED] fix: build error temp fix (#20207)
