feat: complete the group model (god_admin, site groups, aggregates), enforce naming, fix docs 500s + status dots (v1.26.0)

- seed god_admin + nest into app_super_admin; auto-provision site groups (S_super_admin, S_hosts_*/S_apps_* aggregates, S_everyone) on site create + self-heal on Directory load
- map service resources to the app kind (site_local_app_<slug>_*); nest per-resource groups into site aggregates (physical inheritance lattice)
- enforce the group naming convention server-side on POST /groups; surface god_admin + site groups on the site resource modal
- fix in-app /docs/<slug> 500s (Dockerfile never copied docs/); serve doc images at /docs/images
- fix Directory status dots (neutral grey when agent endpoint unreachable); align Profile/API cards full-width
- group resolver: keep the site slug verbatim (site_local not re-slugified)
- bump to 1.26.0
