### ✅ Security Attack Tests (5 attacks blocked)

#### Attack 1: Negative Amount Injection
```javascript
Livewire.find('pay-component-id').set('amount', -50);
```
- **Expected:** Blocked
- **Result:** ✅ BLOCKED
- **Log:** `[TRANSFER] Security: Invalid payment amount (must be positive number)`
- **Code:**
```php
if (!is_numeric($amount) || $amount <= 0) {
    return $this->logAndReport('Security: Invalid payment amount...');
}
```

#### Attack 2: Zero Amount Injection
```javascript
Livewire.find('pay-component-id').set('amount', 0);
```
- **Expected:** Blocked
- **Result:** ✅ BLOCKED
- **Log:** `[TRANSFER] Security: Invalid payment amount (must be positive number)`
- **Same validation as Attack 1**

#### Attack 3: Invalid ToAccountId Injection
```javascript
Livewire.find('pay-component-id').set('toAccountId', -1);
```
- **Expected:** Blocked
- **Result:** ✅ BLOCKED
- **Log:** `[TRANSFER] Security: Invalid To account ID`
- **Code:**
```php
if (!is_int($toAccountId) || $toAccountId <= 0) {
    return $this->logAndReport('Security: Invalid To account ID...');
}
```

#### Attack 4: Unauthorized Account Access
- **Scenario:** User A logged in, attempt to send from User B's account
- **Expected:** Blocked
- **Result:** ✅ BLOCKED
- **Log:** `[TRANSFER] Unauthorized payment attempt: illegal access of From account`
- **Protection:** Backend ownership check via `getAccountsInfo()`
```php
$accountsInfo = collect($transactionController->getAccountsInfo());
if (!$accountsInfo->contains('id', $fromAccountId)) {
    return $this->logAndReport('Unauthorized payment attempt: illegal access...');
}
```

#### Attack 5: Balance Limit Bypass via Modal Manipulation
```javascript
// Try to bypass limit check by modifying modal state
Livewire.find('pay-component-id').set('isPaymentLimitErrorModalOpen', false);
// Then send payment exceeding limits
```
- **Expected:** Blocked
- **Result:** ✅ BLOCKED
- **Log:** `[TRANSFER] Security: Payment attempt with exceeded balance limits detected`
- **Code:**
```php
$limitsOk = $this->checkBalanceLimits(...);
if (!$limitsOk) {
    return; // Execution stops regardless of modal state
}
```
