check for file size on upload. Make it 500mb?

[LukeLoze1]

Motivation and Context

If file to upload was too big it would blow up in the background (exceptions) but nothing at the frontend

What has changed

Put in support tool UI check for file size at 500mb
set backend limit to 500mb

How to test?

Should work fine locally to prove functionality. In standard dev GCP to test up to 500mb
