Fix audio video config propagation in demo app

[shi-su]

ℹ️ Description

Current demo app logic calls AudioVideoConfiguration(videoMaxResolution) when setting meeting max resolution and this function will override other config selected with default value (i.e., audioMode: stereo48K, callKitEnabled: false, enableAudioRedundancy: true). This change fixes this config propagation issue.
