feat(captcha): add ALTCHA configuration endpoint and integrate into HomeController

- Introduced a new endpoint `/api/v1/altcha/config` in CaptchaController to return the status of the ALTCHA captcha.
- Updated HomeController to inject AltchaService and pass the captcha status to the home page template.
- Modified the home.html.twig template to conditionally render the ALTCHA widget based on the captcha status.
- Updated manifest.json and cache files to reflect changes in the codebase.
