fix(docker): add coreutils so MAX_LIFETIME_SECONDS works on Wolfi base

scripts/app-start.sh invokes GNU `timeout` with --preserve-status and
--foreground when MAX_LIFETIME_SECONDS is set. The Wolfi base only ships
BusyBox `timeout`, which rejects those flags, so the server never starts
and the container restart-loops. GNU coreutils rode in for free on the old
RockyLinux base and was lost in the RockyLinux -> Wolfi switch (PR #423).

Add coreutils to the image to restore GNU `timeout`. Verified against the
real app-start.sh: the server now starts and runs for the full lifetime.
grype shows adding coreutils introduces 0 new CVEs (6 Chainguard-maintained
packages, ~10 MB).

Reported in Pylon 2657. Fixes ENG-1428.

+- **Restore `MAX_LIFETIME_SECONDS` support in the Docker image**: `scripts/app-start.sh` invokes GNU `timeout` with `--preserve-status` and `--foreground`, flags the Wolfi base's BusyBox `timeout` does not support. Setting `MAX_LIFETIME_SECONDS` therefore caused the server to fail to start and the container to restart-loop. Added `coreutils` to the image so GNU `timeout` is available. This regressed when the base image moved from RockyLinux (which shipped GNU coreutils) to Wolfi.
