Refactor endpoints

This is a complete refactor of the API, allowing us to easily switching
from one framework to the other, in our case `lambda_http` and `axum`.

The refactor is done in a way where the endpoints would us the same
logic and same database requests.

This patch also adds a new implementation for using Axum either as a
standalone server (to facilitate local debugging) or as a lambda
function handler.
