Improve request logging in the service

[angelaraya]

Current logs provide unnecessary and repeated information by default, there should be a way to only receive explicitly requested logs. For starters we could reduce logs to only print when hitting /api, since it's our main endpoint.

For a quick tweak, we can adjust how verbose the logger is in https://github.com/janeirodigital/sai-impl-service/blob/main/packages/service/src/componentsMain.ts#L9

levels are described in: https://github.com/digita-ai/handlersjs/blob/main/packages/handlersjs-logging/lib/models/logger-level.ts
