fix: group names match docs, dedupe resource groups, agent 404, shared-secrets + vault apps, promote + plugin logs (v1.27.0) (#168)

- group names match docs/GROUPS.md: {site}_{kind}_{name}_{level} (kind always present; services -> app kind); updated resolver + tests + access_request test
- site resource carries only god_admin + site-wide groups
- groups no longer appear 3x: idempotent ResourceGroup linking (self-heal was creating duplicates on every Directory load)
- /api/agent/* no longer 404s: REST router mounts unconditionally (was gated on the WS server)
- shared-secrets: slug regex allows underscores; GET list uses static pathFor (fixes 's.path is not a function')
- vault Apps tab: new GET /api/vault/apps + Minted apps list + purpose text; /docs/vault help link + docs cover Apps/Shared
- discovery promote: load instance and call update() (fixes 'Resource.update is not a function')
- discovery plugin cards: last-run time/status + Logs button
