release/v1.26.0: complete group model, enforce naming, fix docs + status dots (#166)

* 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

* fix: use verbatim resource slugs in group names (matches access-request tests + live convention)

The group naming inserts a kind segment (resourceGroupCns(site, kind, slug, level)),
but the access-request tests + the live directory convention are verbatim
({site}_{slug}_{level} -- the kind is carried in the resource slug, e.g. host_theta-env).
For bare test slugs this produced site_x_host_artest-host_x_access instead of the
expected site_x_artest-host_x_access, so the requester was never removed from the
auto-provisioned access group and every request 409'd. resourceGroupCns is now
(site, slug, level) with the verbatim slug; the kind is used only to pick the
aggregate the group nests into.
