ci: verify /v3/health after the /v3 route move (fixes dev deploy)

PR #10 moved every REST route under /v3 (health -> /v3/health) but left the deploy job's REST verify step curling $URL/health, which now 404s so curl --fail exits 22 and the dev deploy fails. Point it at /v3/health and also check /v3/version. These hit the *.run.app URL directly (no LB/ESP), so the bare-/v3 LB limitation does not apply here.
