feat(ui): introduce number-flow animation library

[peps]

I found this pretty amazing library for animating numbers, better than what we currently have.

https://number-flow.barvian.me/

The goal of this PR is to add the number-flow library and implement it in a few "Low Risk" areas. This will allow us to test how it impacts performance, and if it's performing well we can begin to implement it in other areas of the app.

Right now it's implemented in the following places:

• Percentage loader on the Setup screen
• Sidebar Gems counter when logged in
• SoS widget timer

A few notes:

• This component requires the value passed to it to be a number, strings wont work. For something like the big Wallet number, we would need to change the approach to our formatting.
• This library adds extra padding around the numbers, so we may need to adjust layout spacing when replacing current numbers.
