Add a UUID-based request-ID middleware using tower-http's request-id
feature. Each inbound request receives a unique x-request-id header
(or preserves a client-supplied one), which is recorded in the tracing
span and propagated to the response.
This enables operators to correlate log lines across the middleware
stack for a single request under concurrent load, and lets clients
reference specific requests in bug reports.
