Add @PreAuthorize annotations to all API controllers (14 endpoints
across 6 controllers) enforcing OAuth2 scopes: apps:manage, apps:deploy,
billing:manage, observe:read, platform:admin.
Enforce tenant isolation: TenantResolutionFilter now rejects cross-tenant
access on /api/tenants/{id}/* paths. New TenantOwnershipValidator checks
environment/app ownership for paths without tenantId. Platform admins
bypass both layers.
Fix frontend: OrgResolver split into two useEffect hooks so scopes
refresh on org switch. Scopes now served from /api/config (single source
of truth). Bootstrap cleaned — standalone org permissions removed.
Update docs/architecture.md, docs/user-manual.md, and CLAUDE.md to
reflect all auth hardening changes.
