Adding the Fallback Pool to the Load Balancing UI and other significant UI enhancements

Cloudflare has introduced a new feature, the fallback pool, for its Load Balancer tool. This feature ensures that traffic is still routed even if all pools are down by directing it to a "pool of last resort." The company has also made updates to its dashboard UI, including adding the fallback pool option and improving other areas of the Load Balancing app. These changes include a facelift for the main Load Balancing page, de-modaling content from modal screens, and adding more information in tables to clarify shared objects among teams. Additionally, Cloudflare has added confirmation modals and updated CTAs/buttons to prevent unwanted changes and improve user confidence when making updates.
