feat: Add granular role-based permissions system with Entra ID integration

- Implement RBAC with viewer/editor/owner roles using bitwise permissions
      - Add AccessRole, AclEntry, and Group models for permission management
      - Create PermissionService for core permission logic and validation
      - Integrate Microsoft Graph API for Entra ID user/group search
      - Add middleware for resource access validation with custom ID resolvers
      - Implement bulk permission updates with transaction support
      - Create permission management UI with people picker and role selection
      - Add public sharing capabilities for resources
      - Include database migration for existing agent ownership
      - Support hybrid local/Entra ID identity management
      - Add comprehensive test coverage for all new services

chore: Update @librechat/data-schemas to version 0.0.9 and export common module in index.ts

fix: Update userGroup tests to mock logger correctly and change principalId expectation from null to undefined
