fix: correct curl syntax for file upload test

Fixed multipart/form-data curl command in validate_services function by
removing quotes around $INPUT_DATA variable. This allows bash to properly
expand the -F options as separate arguments to curl instead of treating
them as a single quoted string.

This resolves the HTTP 000 status error where file upload requests were
failing to reach the server.

Changes:
- Line 134: Removed quotes around $INPUT_DATA in HTTP_STATUS curl command
- Line 138: Removed quotes around $INPUT_DATA in CONTENT curl command
