Fix everything-server-based integration tests (#756)

Browse source 
* Pin `npx @modelcontextprotocol/server-everything` version to `2025.12.18`.
* Replace `tzolov/mcp-everything-server` Docker image with `node:lts-alpine` + `npx` command.
* Handle HTTP 202 special case.
* Fix test assertions.

The recent rollout of everything-server broke integration tests which take the latest version from the node registry.
This PR unifies the everything-server usage - the Testcontainers Docker setup uses the same version as the STDIO npx-based tests and no longer relies on tzolov/mcp-everything-server.
