 * Role entity — tenant-scoped, fully dynamic.

 * - Roles fully dynamic, managed per tenant by Admin — never static role enums
 * - No Super Admin in Phase 1 — Admin is highest role, seeded during tenant onboarding
 *
 * Per scope doc:
 * - Predefined: Admin (full), Operations Manager, Trip Coordinator, Sales Team, Guest (read-only)
 * - Custom roles with granular per-module permissions
