test(services): lock FastMCP server identity to dist name

Fixes M1 from the PR #22 coherence review. server.py:222
constructs FastMCP("python-docs-mcp-server", ...), but no test
asserts that identity. A future rename that touches the
constructor without updating docs (or vice versa) would have
been a silent drift. One assertion locks it.
