✨ Update to latest docker template revision ✨

- .env.scripts: synced version stamp to current template; preserved ENV_PULL_URL=casjaysdev/alpine (gen-dockerfile's --update path had a bug computing "alpine" instead, corrected manually per the casjaysdevdocker->casjaysdev/* base-image convention)
- rootfs/usr/local/bin/entrypoint.sh: regenerated from current template; fixes stale CONTAINER_NAME="alpine" -> "opengist" and normalizes whitespace
- rootfs/usr/local/etc/docker/functions/entrypoint.sh: replaced from template; picks up upstream fix for __symlink/__initialize_ssl_certs returning nonzero on success under set -e
- rootfs/root/docker/setup/00-init.sh, 01-system.sh, 02-packages.sh, 03-files.sh, 04-users.sh, 06-post.sh, 07-cleanup.sh: version stamp bump only, no logic change
- rootfs/root/docker/setup/05-custom.sh: version stamp bump only; restored the opengist binary download/install logic that the template regeneration would have wiped (this file is app-specific, not boilerplate)
