Feature Request: Implement RBAC (Role-Based Access Control) as Auth Presets in Postpipe

[Sourodip-1]

Add Role-Based Access Control (RBAC) to Postpipe as reusable authentication presets, allowing users to quickly enable role-based permissions in their projects without manually setting up access logic.

Problem

Postpipe currently supports authentication, but lacks built-in role and permission presets. This makes it harder for users to create secure multi-user apps with role-specific access.

Requested Improvements

1. RBAC as a Preset in Auth Section

Add RBAC as a selectable preset alongside existing authentication options:

Owner
Admin
Editor
Viewer
Custom roles (optional)

2. Auto-Generated Role Logic

When RBAC is enabled:

Generate role fields in database schema
Add middleware for route protection
Add helper functions for permission checks
Create session/user role handling

3. Template-Level Integration

Ensure generated templates include:

Protected routes
Role-aware UI rendering
Permission-based component visibility

4. Dashboard Support

Allow users to:

Assign roles to team members
View role mappings
Edit access permissions

5. Developer Experience

Make setup simple:

One-click enable in Forge/static presets
Sensible defaults
Clear documentation

Expected Outcome

Faster setup for secure apps
Reduced manual auth boilerplate
Better team collaboration support
Stronger product offering

Priority
Very High
