chore: support admin api v2

Add Optional Support for Admin API v2

Summary

This PR adds optional support for the new Admin API v2 (https://api.aem.live) while maintaining full backward compatibility with the existing Admin API v1 (https://admin.hlx.page). Sites can now opt-in to using API v2 by specifying apiVersion: 2 in their configuration.

Changes

Core Implementation

• Added new API v2 constant in src/extension/utils/admin.js:

  • Added ADMIN_ORIGIN_V2 = 'https://api.aem.live' alongside existing ADMIN_ORIGIN
  • Updated comments for clarity: "Admin API v1" and "Admin API v2"

• Enhanced API routing logic:

  • When apiVersion === 2 is specified, routes requests to API v2 origin
  • API v2 uses different URL patterns for login/logout/profile endpoints
  • Defaults to API v1 (current behavior) when no version is specified

• Added default value in src/extension/app/store/site.js:

  • Set apiVersion = 1 as the default to ensure backward compatibility

Backward Compatibility

✅ No breaking changes: All existing sites continue to use API v1 by default. API v2 is strictly opt-in via configuration.

How to Use API v2

Sites can opt-in to API v2 by adding apiVersion: 2 to their sidekick configuration:

{
  owner: 'adobe',
  repo: 'aem-boilerplate',
  apiVersion: 2  // Optional: Use API v2
}
