Error Handling: Create Region w/ Same Name as another Region

[JGDoh]

Describe the bug Currently, the way we display this error "Create Region w/ Same Name as another Region" isn't the same way we handle errors across the App. I can't access this state because I just created a region but the error handling should look more like what is below:

I've already communicated this error to @RaulUrtecho as well.

To Reproduce Steps to reproduce the behavior:

1. Go to 'Region'
2. Click on 'Create Region'
3. Try to enter a region name that already exists: i.e. bali
4. See error handling

Expected behavior The error message should be uniform to how we handle errors of this type. See onboarding errors.
