Upgrade dotenv 16.6.1 -> 17.2.2

[andygout]

This PR upgrades dotenv to the current latest version.

If the changes in src/dotenv.js are not applied then unnecessary logs will appear in the server logs (those in the below sample that start with [dotenv@17.2.2]).

This is owing to the change introduced in v17: https://github.com/motdotla/dotenv/blob/master/CHANGELOG.md#1700-2025-06-27:

Default quiet to false - informational (file and keys count) runtime log message shows by default (motdotla/dotenv#875)

> dramatis-api@0.0.0 start
> npm run setup && node --watch-path=src --watch-preserve-output src/app.js


> dramatis-api@0.0.0 setup
