fix: fetch race condition

[andreaskienle]

This PR resolves a race condition triggered during MCP page re-renders, for example, when opening the YAML splitter from the MCP header.

The reason was that useApiResource used the SWR key ⁠[resource.path, apiConfig] while fetching the same MCP resource with different configs (depending on excludeMcpConfig being true/false). Because both responses shared the same SWR key, the full response occasionally overwrote the smaller one in the cache. This lead to issues when expected fields were missing.

I now added excludeMcpConfig to the SWR cache key, so we have separate entries in the cache.
