* Refactor captcha implementation and integrate new captcha components

- Removed the old RecaptchaV2 component and replaced it with a new implementation that supports both reCAPTCHA and hCaptcha through a unified CaptchaInput component.
- Updated the OpenForm component to utilize the new CaptchaInput for dynamic captcha rendering based on user-selected provider.
- Cleaned up the package.json by removing the deprecated @hcaptcha/vue3-hcaptcha dependency.
- Enhanced form initialization to set a default captcha provider.
- Improved error handling and cleanup for both reCAPTCHA and hCaptcha scripts.

These changes streamline captcha integration, improve maintainability, and enhance user experience by providing a more flexible captcha solution.

* Refactor captcha error messages and localization support

* Refactor registration process to integrate reCAPTCHA

- Replaced hCaptcha implementation with reCAPTCHA in RegisterController and related test cases.
- Updated validation rules to utilize g-recaptcha-response instead of h-captcha-response.
- Modified RegisterForm component to support reCAPTCHA, including changes to the form data structure and component references.
- Enhanced test cases to reflect the new reCAPTCHA integration, ensuring proper validation and response handling.

These changes improve security and user experience during the registration process by adopting a more widely used captcha solution.

* Fix reCAPTCHA configuration and update RegisterForm styling

- Corrected the configuration key for reCAPTCHA in RegisterController from 'services.recaptcha.secret_key' to 'services.re_captcha.secret_key'.
- Updated the styling of the Captcha input section in RegisterForm.vue to improve layout consistency.

These changes ensure proper reCAPTCHA functionality and enhance the user interface during the registration process.

* Fix reCAPTCHA configuration in RegisterTest to use the correct key format

- Updated the configuration key for reCAPTCHA in RegisterTest from 'services.recaptcha.secret_key' to 'services.re_captcha.secret_key' to ensure proper functionality during tests.

This change aligns the test setup with the recent updates in the reCAPTCHA integration, improving the accuracy of the registration process tests.
