Type of change?	Bug fix

Symptom (bug) / Objective (enhancement)

• In src/Core/Notification/Action/_ActionWebhook.php, the code referenced $this->m_aWebrequestErrors instead of the correct $this->aRequestErrors, causing runtime errors.
• The same file had a syntax error: case WebRequestSender::ENUM_SEND_STATE_ERROR; (semicolon instead of colon).
• In tests/php-unit-tests/_ActionWebhookTest.php, unused imports (Exception, ReflectionException) were present.

Reproduction procedure (bug)

2. With module version x.y.z

3. With PHP x.y.z

4. Trigger a webhook action that results in an error (e.g., invalid callback signature).

5. Observe PHP notices about undefined property or syntax errors in logs.
   -->

6. On iTop 3.x.x

7. With module version 1.x.x

8. With PHP 7.4+ or 8.x

9. Trigger a webhook action that should log errors (e.g., misconfigured callback).

10. See PHP notice: "Undefined property: ...m_aWebrequestErrors"

11. See parse error if the switch case is hit.

Cause (bug)

• Typo in property name: should be $this->aRequestErrors
• Syntax error in switch statement: should use colon, not semicolon

Proposed solution (bug and enhancement)

• Corrected property name in _ActionWebhook.php
• Fixed switch case syntax
• Removed unused imports in _ActionWebhookTest.php

Hello, thank you for your PR and for correcting errors :)
I just have a question : ReflectionException seems to be used in the PHPDoc of testCheckCallbackSignature, why do you suggest removing it ?
