Julian Appel fa96be2d42 Fix crash handling and log noise in logging feature
Review of the logging work from the previous commit turned up a real
correctness issue: the uncaughtException/unhandledRejection handlers
logged the error but let the process keep running, which silently
disabled Node's default crash-on-fatal-error behavior and could leave
a zombie process serving broken requests instead of restarting. Both
processes now log and then exit(1); restart: unless-stopped is added
to both services so Docker actually brings them back up.

Also: harden the logger against JSON.stringify throwing on
non-serializable meta, log aborted (closed-before-finished) requests
in the API access log, and stop the Next.js proxy from logging the
Docker healthcheck's request to "/" every few seconds so real
navigation events aren't drowned out.
