Summary

This is a PoC to validate the proposal to migrate the checks for existing tags from the client to the server side. Do not merge.

Local WP "just works" in my testing.

For those still using a WP Local Docker dev environment, add this extra_hosts entry to /path/to/wp-local-docker-sites/sitekit-10uplabs-com/docker-compose.yml, pointing the dev site's domain name to the gateway IP address:

extra_hosts:
  - "sitekit.10uplabs.com:10.0.0.3"

Addresses issue:

• Migrate client-side existing tag checks to backend endpoints #10700
