fix: [IOAPPX-500] IOScrollView interpolated opacity check of NaN values (#7094)

## Short description
This PR refactors the `opacityTransition` logic in the `IOScrollView`
component to improve robustness and handle edge cases where the
interpolated opacity could result in `NaN`. (Thanks @shadowsheep1)
Without this fix, opening the IO app via the `ioit://main/wallet`
deeplink can cause a crash.

## List of changes proposed in this pull request
* Updated the `opacityTransition` to explicitly check if
`interpolatedOpacity` is `NaN` and default to `0` in such cases,
ensuring the opacity value is always valid.

## How to test
Ensure that opening the app via the `ioit://main/wallet` deeplink does
not cause the app to crash.
