Some improvements for logging and loading configuration

Some improvements for logging and loading configuration:

• Logger parameterization for a more clear log showing directly the level and datetime and using the level that is configured in the config.yaml file: {"level":"INFO","time":"2024-05-10T13:34:03.761Z","pid":45617,"hostname":"wmf3277","msg":"mpic has started listening on port 80"}
• Some changes to load configuration and logger using the same configuration.js file
• Logging the validation form error with details
• Adjusted the level for some logs
• Added form validation to the patch endpoint
