♻️ Refactor cocurrency model on backend

Mainly the followin changes:

- Pass majority of code to the old and plain synchronous style
  and start using virtual threads for the RPC (and partially some
  HTTP server middlewares).
- Make some improvements on how CLIMIT is handled, simplifying code
- Improve considerably performance reducing the reflection and
  unnecesary funcion calls on the whole stack-trace of an RPC call.
- Improve efficiency reducing considerably the total threads number.
