Passing duration=0 is more logical and less superfluous
* Refactor UploadBar to handle state more correctly
* Change ProgressBar to new useSmoothAnimation signature and default animated to true for consistency
* Add type guard
* Make types stricter
* Write tests for the ProgressBar component
* Make the new test conform to tsc --strict
* Update UploadBar.tsx
* Update UploadBar.tsx
* Update UploadBar.tsx
