feat: v1.17.2 post-deploy fixes + SMS/TOS on /conf

- auto-slug plugins (no more manual slug field)
- plugin schedule dropdown (hourly/daily/weekly + custom)
- fix /vault secrets-list 403 (per-user/app/admin list grants on dir path;
  ensurePolicy always re-writes so existing policies get the grant)
- fix /profile literal {{...}} tags (header uid span, members label id,
  admin-actions moved inside jq-repeat=user scope)
- fix plugin editing (Edit modal non-secret only; secrets have own modal)
- nmap: apk add nmap in Dockerfile.openldap + clearer missing-binary error
- add SMS (VoIP.ms) config card to /conf (password masked, leave-blank-to-keep)
- move Terms of Service editor from Overview to /conf
