enhancement: Resolve default usernames from environment variables

[O2sa]

Currently, the default usernames in the CompareForm component are hardcoded to pbiggar and CoralineAda. We should resolve these from environment variables (e.g., NEXT_PUBLIC_DEFAULT_USER1 and NEXT_PUBLIC_DEFAULT_USER2) to make them easily configurable without changing the code.

Tasks

• Open components/compare-form.tsx.
• Update the useState initial values for username1 and username2 to read from process.env.NEXT_PUBLIC_DEFAULT_USER1 and process.env.NEXT_PUBLIC_DEFAULT_USER2 (providing an empty texts as fallbacks).
• Document the new variables in .env.example.
