Health endpoint doesn't check DB

What it is

A health endpoint returns 200 unconditionally without checking the database or other dependencies it needs to do its job.

Why it matters

It answers the wrong question. The process is alive, so the check passes, while every request fails on a connection the check never tried — and the load balancer keeps the instance in rotation throughout.

How to fix it

Have readiness run a cheap real query — SELECT 1 with a short timeout — against each critical dependency. Keep liveness trivial so a dependency blip restarts nothing.
