Fix reCAPTCHA loading and add Yandex Cloud support

[Copilot]

reCAPTCHA was failing to load due to incomplete domain coverage and missing iframe/cookie configurations. Added Yandex Cloud deployment support and Yandex SmartCaptcha integration.

CAPTCHA Domain Coverage

• Added missing reCAPTCHA domains: www.gstatic.com/recaptcha, recaptcha.net/*, generic google.com and gstatic.com
• Added hCaptcha domains: js.hcaptcha.com, newassets.hcaptcha.com
• Added Yandex SmartCaptcha domains: smartcaptcha.yandexcloud.net, yandex.com/showcaptcha, yastatic.net/s3/captcha-frontend
• Synchronized domain lists across client (captcha-handler.ts) and service worker (sw.js)

CAPTCHA Functionality Improvements

• Added allow-popups sandbox permission and strict-origin-when-cross-origin referrer policy to CAPTCHA iframes
• Enhanced cookie handling to detect and properly configure cookies for all CAPTCHA providers (reCAPTCHA, hCaptcha, Cloudflare, Yandex)
• Initialized window.smartCaptcha global object for Yandex SmartCaptcha API

// Before: Limited domain coverage
const CAPTCHA_DOMAINS = [
    "google.com",
    "recaptcha.net",
    "gstatic.com"
];

// After: Comprehensive coverage for all CAPTCHA providers
const CAPTCHA_DOMAINS = [
    // Google reCAPTCHA
    "google.com/recaptcha",
    "www.google.com/recaptcha",
    "gstatic.com/recaptcha",
    "www.gstatic.com/recaptcha",
    // Yandex SmartCaptcha
    "smartcaptcha.yandexcloud.net",
    "yandex.com/showcaptcha",
    // ... (27 total domains)
];

Yandex Cloud Deployment

• Added deployment guide for Yandex Compute Cloud (VM and Docker)
• Documented systemd service configuration
• Included Yandex Object Storage integration notes

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• telemetry.astro.build
  • Triggering command: node /home/REDACTED/work/Radius/Radius/node_modules/.bin/astro build (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt
