This is a lot of small improvement to make aleph-vm more usable. I'm putting them all under the banner of the Jira tickets : ALEPH-166

• Better logging
• Include the VM hash in logs were relevant (might have missed some place yet) to help debug endpoint
• Remove the duplicate output of the db logs (sqlalchemy)
• Ensure logs for http request are printed
• Set default level for logging to INFO (so node owner have useful info by default for debugging problem)
• Improve the developer documentation
• Fix some tests precondition
• Fix docstirngs
• Fix hatch fmt command (and ruff fmt )
• Less crap in the program output in general
• Don't check payment for fake debug instances.
• Ability to set the LOG level via an environment variable (replace Fix: Log level could not be configured from settings #581 )
