fix: repair memlimits script and finish #685 apply pass

Env var name mismatch (CLOUDRON_API_TOKEN), dash echo corrupting the
1MB apps JSON (backslash escapes), scheme-prefixed fqdn filter that
matched nothing, unset curmbMB under set -u, and the wrong endpoint
(POST /configure/memory_limit is the real route). Apply now complete:
15/16 were already at target; photos floor-limited 4096->3584 (Immich
manifest floor), task 15687, healthy.
