refactor: reimplement csv option for domains

[erika-wallace]

Description

W-19830244

This PR reimplements --csv for heroku domains, since it was removed from oclif during the migration to v4. It allows users to output domain data in CSV format and export to a .csv file.

Type of change:

Refactor

Testing

NOTE: You will need an app with multiple domains (at least 3-4 to test sorting).

Test CSV output:

1. checkout this branch and run npm install && npm run build
2. Run ./bin/run domains -a <your-app> --csv, confirm CSV output with headers
3. Run ./bin/run domains -a <your-app> --csv > test-output.csv, confirm file was created successfully and opens with proper CSV format

Test CSV sorting:

4. Run ./bin/run domains -a <your-app> --csv --sort "Domain Name", confirm CSV output was sorted by the Domain Name column (direct property)
5. Run ./bin/run domains -a <your-app> --csv --sort "DNS Record Type", confirm CSV output was sorted by the DNS Record Type column (not a direct property)

Test CSV with other flags:

6. Run ./bin/run domains -a <your-app> --csv --extended, confirm output includes additional columns (ACM Status, ACM Status Reason)
7. Run ./bin/run domains -a <your-app> --csv --columns "Domain Name,DNS Target", confirm output only shows specified columns
8. Run ./bin/run domains -a <your-app> --csv --filter "Domain Name=example", confirm output only shows domains matching the filter criteria

Verify no regressions:

9. Run ./bin/run domains -a <your-app>, confirm table output still works
10. Run ./bin/run domains -a <your-app> --sort "Domain Name", confirm table sorting still works

Note: The sorting for CSV is different from the table sorting, so the outputs don't match exactly. The table is sorted by oclif/table, which uses the natural-orderby package. Let me know if we should align them. I can import natural-orderby for CSV too.

Fantastic work here! Well organized and refactored. I requested a few changes, but otherwise, this PR is looking good! I think we should maintain the same sorting between the table and CSV to maintain consistency.

@zwhitfield3 I updated the code with your suggestions and added natural-orderby as a dependency to maintain consistency of sorting between the table and CSV output

Looks good! Thank you for making those updates!
