Supabase Auth: SSO, Mobile, and Server-side support

Supabase has announced new features for its authentication system, including Single Sign-On (SSO) support using SAML 2.0, better support for server-side rendering and mobile apps with PKCE, and native Apple login on iOS. The SSO feature allows users to log in with their company's identity provider, making it easier for developers to build applications for enterprises. Supabase has also introduced the Proof Key for Code Exchange flow (PKCE) authentication flow to improve security for mobile apps and server-side rendering. Additionally, native Apple login on iOS is now supported, allowing users to sign in with their Apple IDs directly within an app.
