This change adds a 'Use Default' button next to the bitrate slider that resets the bitrate to the default value for the current resolution/FPS. It also implements an autoAdjustBitrate setting that controls whether the bitrate is automatically updated when resolution/FPS/YUV444 settings change.
- When the user manually adjusts the bitrate slider, autoAdjustBitrate is set to false
- When the user clicks the 'Use Default' button, autoAdjustBitrate is set to true
- Bitrate is only updated automatically when settings change if autoAdjustBitrate is true
