Refactor: Allow users to scan QR codes even after exceeding max faile…

…d attempts.

- Removed unnecessary functions that returned Flows in FormValidator.
- Introduced a new composable `PreMeasuredContentWithAnimatedVisibility` to pre-measure content height so that when we don't want to change the height of a layout (e.g. resulting in "pushing" the content up in a Column etc) when content with AnimatedVisibility shows/hides.
- Updated QR scanning screen to use the new composable for displaying informative text.
- Updated unit tests.
