Description
Description
We need a proper middleware mechanic in the server code. This must support adding custom Starlette middlware and have a pre-defined order of middleware when auth is enabled. See FastMCP 2.0 for inspiration.

Research direction
The issue names only the server code and custom Starlette middleware; start by locating the existing middleware and authentication setup, then compare the intended approach with FastMCP 2.0. Done means custom middleware can be added and its order is predefined when authentication is enabled, but the issue names no files or tests.
