### Description
Improved the `docker/example.env` file to make it more beginner-friendly
and easier to configure for self-hosters.
Changes made:
- Added section headers for clarity (e.g. Required Config, Firebase
Config, etc.)
- Clarified which settings are optional (Firebase, email, ports)
- Added better inline comments explaining each env variable
- Improved formatting and spacing for better readability
