fix(rbac): make complete built-in RBAC available on Community (#1793)

Open all five built-in global roles and stack/node scoped assignments
on Community. Remove paid fences from user role create/update, scoped
assignment CRUD, permission evaluation, and the Users settings UI.

Admiral continues to own extended audit governance, LDAP directory
integration, and other organizational assurance features. Built-in
scoped RBAC is no longer marketed or enforced as paid-only.
