Phase 1: Fix stale/broken feature tests

[dkwiebe]

Summary

Two feature test files reference a role column on the users table and an isAdmin() method that no longer exist in the current schema. These tests likely fail against the current database structure.

Affected Files

• tests/Feature/AuthenticationTest.php
• tests/Feature/UserRoleAuthorizationTest.php

Problem

These tests call:

User::factory()->create(['role' => User::ROLE_ADMIN])
$user->isAdmin()

The current User model uses:

• A super_admin boolean column for platform-level access
• A role pivot column on project_user for per-project roles

Implementation

Update all references in both test files:

• Replace ['role' => User::ROLE_ADMIN] → ['super_admin' => true]
• Replace $user->isAdmin() → $user->isSuperAdmin()
• Ensure factory state matches current schema

Acceptance Criteria

• php artisan test passes with zero failures in these two files
• No test references removed role column or isAdmin() method
