Fix TypeError in groups.php when database operations fail

[Copilot]

database->select() returns false on connection failure or PDO exceptions. Calling count() on this in PHP 8+ causes a fatal TypeError, preventing system initialization during upgrades.

Changes

• Line 462: Guard count($result) with is_array() check
• Line 531: Guard $num_rows === 0 comparison with !== false check
• Both checks use strict comparison (===) to prevent type coercion

// Before
if (count($result) == 0) {

// After  
if (is_array($result) && count($result) === 0) {

When database operations fail, the code now skips default group/permission creation instead of crashing.

Original prompt
