Email spam security (#641)

* Add hCaptcha on register page

* register page captcha test cases

* Refactor integration validation rules to include form context

- Updated the `getValidationRules` method in various integration handlers (Discord, Email, Google Sheets, Slack, Webhook, Zapier) to accept an optional `Form` parameter, allowing for context-aware validation.
- Enhanced the `EmailIntegration` handler to enforce restrictions based on user plans, ensuring free users can only create one email integration per form and can only send to a single email address.
- Added a new test suite for `EmailIntegration` to validate the new restrictions and ensure proper functionality for both free and pro users.
- Introduced loading state management in the `IntegrationModal` component to improve user experience during save operations.

These changes improve the flexibility and user experience of form integrations, particularly for email handling.

* for self-hosted ignore emil validation for spam

* fix pint

* ignore register throttle for testing env

* support new migration for mysql also

* Register page captcha enable if captcha key set

* fix test case

* fix test case

* fix test case

* fix pint

* Refactor RegisterController middleware and update TestCase setup

- Removed environment check for throttling middleware in RegisterController, ensuring consistent rate limiting for the registration endpoint.
- Updated TestCase to disable throttle middleware during tests, allowing for more flexible testing scenarios without rate limiting interference.

* Enhance hCaptcha integration in tests and configuration

- Added hCaptcha site and secret keys to phpunit.xml for testing purposes.
- Updated RegisterTest to configure hCaptcha secret key dynamically, ensuring proper token validation in production environment.

These changes improve the testing setup for hCaptcha, facilitating more accurate simulation of production conditions.
