feat: add cross_app_access_requesting_app support for connections (EA)

[ankita10119]

🔧 Changes

Adds schema support for the cross_app_access_requesting_app connection property introduced by the Cross App Access (CAA) feature.

What changed:

• Added cross_app_access_requesting_app to the connections JSON schema src/tools/auth0/handlers/connections.ts. The field accepts { active: boolean } and follows the same pattern as the existing authentication and connected_accounts fields.

No additional handler logic was required, the property flows through the existing export and deploy paths automatically, as the auth0 Node SDK (^5.13.0) already includes the CrossAppAccessRequestingApp type on ConnectionForList.

Usage:

connections:
  - name: enterprise-oidc
    strategy: oidc
    cross_app_access_requesting_app:
      active: true

🔬 Testing

Requires the token_vault_xaa feature flag enabled on the tenant.

Unit tests - added to test/tools/auth0/handlers/connections.tests.js:

• Schema accepts cross_app_access_requesting_app with active: true/false
• Schema rejects unknown properties (additionalProperties: false)
• Property passes through unchanged in the connections.update payload

Manual end-to-end test (verified on dev-ankita-t.us.auth0.com with flag enabled):

1. Exported tenant - cross_app_access_requesting_app absent from OIDC connection
2. Added cross_app_access_requesting_app: active: true to the connection in tenant.yaml
3. Deployed - API accepted the property, connection updated successfully
4. Re-exported - cross_app_access_requesting_app: active: true present in exported YAML

Round-trip confirmed. Attempted deploy without the feature flag returns operation_not_supported (400) from the API - expected behavior, no special handling needed in the CLI.
