Add Multi-Level Admin Roles (Sudo & Non-Sudo Admin)

This will require implementation of Scoped API tokens and presets for built-in integrations , if it did managed to somehow get into Remnawave, possible and better way for it to get implemented is through scoping via API endpoints/Squads and even a higher level of restrictions of Quota to let SuperAdmin (Sudo) decide to give away what permission to the Admin user they are creating.
