Self-heal encryption key file permissions to 0600 on startup. Increase
minimum password length from 6 to 8 characters per NIST SP 800-63B.
Remove console.log statements that exposed file paths, .env locations,
stack names, and admin usernames to stdout.
* feat(rbac): add Deployer & Node Admin roles with scoped permissions (Team Pro)
Add intermediate RBAC roles gated to Team Pro tier:
- Deployer: can deploy/restart/stop/start stacks but cannot edit compose files, delete stacks, or access system settings
- Node Admin: full stack and node management within scope, no system settings access
- Scoped permissions: assign roles per-stack or per-node for fine-grained access control
- Permission engine with checkPermission/requirePermission guards replacing requireAdmin on stack/node routes
- Frontend can() function with /api/permissions/me endpoint for client-side permission checks
- User management UI updated with 4-role selector and scoped permission editor
- Documentation updated with permission matrix, scoped permission docs, and screenshots
* fix(rbac): remove unused RoleAssignment import to fix lint error
