To improve `CI` quality the following checks were added:
* compile warnings
* deprecated dependencies
* insecure dependencies
* unused dependencies
* code vulnerabilities
Also, to improve `CI` execution time, dependencies checks and lining were separated from the test pipeline.
Last, but not least, to make local development easier a `Dockerfile` was created to contain any system dependencies, and targets to handle database creation and migration were added.
