docker: fix healthcheck so the HTTP check actually runs

The condition '[ ${SKIP_CADDY} ! "true" ]' is invalid test syntax and
evaluated false in every configuration, so the curl check against /up
never ran and only php-fpm's FCGI socket was verified. A wedged Caddy or
fatally erroring app still reported healthy.

Also probe every 30s instead of 5m so failures are detected promptly, and
raise start-period to 2m since boot runs migrations and filament:optimize.
