Finishing touches AND FIXES to playground

I added finishing touches to the playground and also fixed memory_add endpoint which used fire-nd-forget approach which unfortunately is not allowed on vercel :(

This simple problem caused a lot of headache

I needed to migrate entire function to cloudflare.
It landed on claudflare queues which means that now i have an entire queue system build for backend api xD

NEW FEATURE

request_admin_access i added button to request admin access !
