Shorten duration of replay rewind animation

[p-malecki]

This PR shortens duration of rewind animation to improve the usability of the rewind feature. The longer version of the animation is played only the first time a user accesses this feature. We track this by storing a variable called "wasReplayRewindIntroduced" in localStorage.

Testing:

Inspect the wasReplayRewindIntroduced state using the Storage Inspector in WebView Developer Tools. Initially, before the 'introduction' of the rewind feature, this variable should not exist. After the feature is first used, it should be created with the value "true". Ensure that the duration of the first replay is 1 second longer than every subsequent replay.

Don't think there's a lot of value in adding extra persistent state just to show longer animation. We should just decide on the length (1.5sec should be ok I believe) and use it at all times (or remove this animation entirely)

The previous animation duration was 1.6 sec, so reducing it to 1.5 seconds wouldn't make a significant difference. We agreed experimentally that 0.6 seconds is the best duration for usability, but that may be too fast for the first impression of rewind animation.
If we decide to drop the idea of a longer first animation, I think we should settling on 0.6 sec.
