fix: LEAP-1490: Fix AudioUltra working with relations and comments

[Gondragos]

This PR fixes the way AudioUltra works with Relations and linking comments (it didn't work and that was a regression), and some small bugs related to AudioUltra itself.

• getting AudioRegion bbox based on in-model values
• reusing propertyWatcher to observe changes in onscreen region position
• adding active state for the region to separate it from highlighted one to prevent them canceling each other
• moving in-canvas region y-coordinates to getters and fixing its height (taking into account timeline size)
• fixing inViewport conditions. viewport might be based on the canvas size only as it's the real element's frame.
• adding inner event on Waveform to indicate current visible frame state on each redraw
• using that event, storing the frame state in the model to catch the moment when we need recalculating region bbox
• adding on-region listeners to apply highlightability
• integrating linking modes logic on selecting audioultra region
• Fix sticking in highlighted status

Looks great 😎, just a suggestion on the snake_case -> camelCase, but logically speaking that won't affect this getting tested. Accidentally approved prematurely, taking this back to when the PR is considered for review officially.
