Subject: [PATCH] feat(rpc): add /health endpoint on the metrics server

Adds a plain GET /health liveness probe on the metrics port (5054),
reusing the existing get_health handler. Covers the route with two
unit tests: one asserting status/content-type/body, one regression
check that /metrics still returns 200.
