FCE-3229 add general set received track quality method

Description

Adds a general setReceivedTracksQuality method to usePeers hook.

FCE-3229 Add `setReceivedTrackQuality` method to `usePeers`

[Copilot]

Pull request overview

Adds a stable, general-purpose setReceivedTrackQuality function to the usePeers hook so consumers can change received track quality without relying on per-track methods that are awkward to use in useEffect.

Changes:

• Add setReceivedTrackQuality callback to usePeers.
• Update the usePeers return object/documentation to expose the new method (and remove the legacy peers alias).
