* fix(mcp): use computed base_internal_url instead of static default
Pass the actual base_internal_url (computed from the runtime port) to
the MCP backend instead of using the static BASE_INTERNAL_URL which
defaults to http://localhost:8000. This fixes internal API calls when
the server runs on a non-default port.
