fix: remove fragile URL fallback from MyOpenCRE CSV download

[PRAteek-singHWY]

Summary

This PR fixes a bug on the MyOpenCRE page where the CSV download button could fail with a 404 Not Found error.

What Changed

• Removed a manual includes('localhost') check that would mistakenly overwrite the backend URL to http://127.0.0.1:5000 (silently stripping away the required /rest/v1 namespace).
• Updated the fetch call to simply use the global ${apiUrl}/cre_csv.

This ensures the /rest/v1 prefix is always safely attached, matching how the file upload component right beneath it handles requests.

Note: Per the CONTRIBUTING.md guidelines for quick fixes taking less than 30 minutes, I am submitting this PR directly rather than opening a separate Issue.

Hi @Pa04rth, this is a quick 1-line routing fix for MyOpenCRE directly as a PR. (So no issue was created as per guidelines)

The CSV download was occasionally losing its /rest/v1 prefix due to an old fallback check, throwing 404s in local dev environments. I removed the check and wired it directly to the global apiUrl so it always routes correctly.

Reviewed — removes fragile localhost fallback that stripped /rest/v1. Uses apiUrl consistently with upload. Merging.
