Performance improvements to Appwrite Cloud

We've made several updates to improve performance on Appwrite Cloud:

• Increased the default CPU for function runtimes on the free tier from 0.5 CPU to 1 CPU.

• Updated Python runtimes to include the --preload flag in Gunicorn, resulting in faster cold starts.

• Improved the rules fetching logic in the Appwrite router to make better use of caching, reducing latency by up to 50ms for functions executed via domains.

• Updated Redis HA clusters to improve redundancy and high availability for caching, queues, pub-sub, and shared state services.

• Adjusted our API and CDN compression logic to avoid compressing small responses, improving performance and making usage stats more accurate.

These updates aim to make your projects faster and more reliable, especially under high-demand scenarios.
