fix(database): make the Redis health check ping with the password

The check was [CMD-SHELL, redis-cli, ping], so Docker ran only redis-cli
and it always passed. redis-cli also exits 0 on NOAUTH and LOADING.
The check now pings with the server password and requires PONG. With a
custom redis.conf that sets its own requirepass, it requires PONG or NOAUTH.
