feat: Add ENV var to use JSON logging

[kasey-alusi-vcc]

Description

This PR adds a new environment variable PRETTY_LOGS_ENABLED to be able to override the default log format with JSON formatted logs. Default behavior will remain pino-pretty. JSON logging can be set with PRETTY_LOGS_ENABLED=false.

Fixes: #4498

Testing Guide

1. Tested by running the service with PRETTY_LOGS_ENABLED=false, validating that log messages are in json format.
2. Also tested without PRETTY_LOGS_ENABLED set at all, and confirmed that there is no change in log format.

LG, could you also add this new var to the .env example files env.http.example and env.ws.example?

Hey @kasey-alusi-vcc, there was an issue where a Dependabot PR corrupted the package-lock.json file, which caused all the current CI failures. The fix has been merged into main, so could you please do a quick rebase to get the CIs running again? Sorry for the inconvenience
