🐛 Bug Fix: Wildcard Permissions (*) Not Working With Empty User Permissions

Problem

When users have no permissions (empty array []) or when permissions are manually passed as an empty array, wildcard patterns like * were not working as expected. This broke the intended behavior where certain components should be visible to all users regardless of their permission status.

Before this fix:

// User with permissions: []
<Can permission="*">Dashboard</Can>           // ❌ Hidden (incorrect)
<Can permission="* || admin">Menu</Can>       // ❌ Hidden (incorrect)

After this fix:

// User with permissions: []
<Can permission="*">Dashboard</Can>           // ✅ Visible (correct)
<Can permission="* || admin">Menu</Can>       // ✅ Visible (correct)
