fix(infra): correct Jaeger image tag

`jaegertracing/all-in-one:1.62` does not exist on Docker Hub —
Jaeger 1.x publishes only full-semver tags (1.X.Y), not rolling
minor tags. Activating the `observability` profile failed at pull
time:

    Error response from daemon: failed to resolve reference
    "docker.io/jaegertracing/all-in-one:1.62": ... not found

Pin to `1.76.0`, the most recent stable in the 1.x line. Renovate's
docker-compose manager will surface future bumps automatically
(gated behind dashboard approval for majors per renovate.json).
