Pull Request Overview
This PR implements comprehensive backend changes to support PKCE OAuth integration and fixes critical domain configuration errors that were preventing OAuth callbacks from working in production. The implementation enhances PKCE validation, adds environment-specific domain configuration, creates user-friendly success/error pages, and improves monitoring capabilities.
Key changes include:
- Fixed incorrect production domain (
mwapsp.shibari.photo→mwapps.shibari.photo) and implemented dynamic domain configuration - Enhanced PKCE validation with RFC 7636 compliant challenge verification using crypto-based SHA256 validation
- Added OAuth success/error pages with popup communication and auto-close functionality

String interpolation in postMessage could be vulnerable to XSS attacks. The tenantId and integrationId values should be properly escaped or validated before being embedded in the HTML response.

The success rate calculation is flawed. Both PKCE and traditional flows are being counted in the same variables (pkceSuccesses/pkceTotal), making the metrics meaningless. The code should track PKCE and traditional flows separately.

The ALLOWED_REDIRECT_HOSTS array is still being defined but appears to be unused since the code now uses getAllowedRedirectHosts() method. This creates potential confusion and should be removed to avoid maintaining duplicate domain lists.

Direct string interpolation of user-controlled data (integrationId) into HTML without escaping could lead to XSS vulnerabilities if the integrationId contains malicious content.
