fix typo

Moved Wallet Controller and types out of the Api

Renamed the folder including the solution to Breeze.

The idea is to now have the web API and the wallet as features (FullNodeFeature) of the Full node, and to have a deamon that gets started by the GUI and that starts the FullNode that will in turn start the API so that the GUI and the FUllNode can communicate.

Optimize project setup

- Added Web api wrapping the Safe functionality offered by HBitcoin
- Added basic unit tests project for the controllers
