Migrate tools Docker image to the new build-time config architecture.
- rootfs/root/docker/setup/03-files.sh: rewrite to canonical form with /tmp/bin, /tmp/var, /tmp/etc, /tmp/usr handlers
- rootfs/usr/local/etc/docker/functions/entrypoint.sh: update to latest template with __init_service_conf, __find_php_ini, __find_php_bin helpers
rootfs/root/docker/setup/03-files.sh
rootfs/usr/local/etc/docker/functions/entrypoint.sh
Update the embedded entrypoint copies in rootfs/ to match the
upstream template change. Internal state files renamed to dotfiles
so they're not matched by `/run/*.pid` cleanup globs:
- /run/init.d/entrypoint.pid -> /run/.entrypoint.pid
- /run/no_exit.pid -> /run/.no_exit.pid
- /run/backup.pid -> /run/.backup.pid
- /run/__start_init_scripts.pid -> /run/.start_init_scripts.pid
Per-service PIDs in /run/init.d/ are unchanged.
