Refactor the streaming display logic for the 14900k host to use the
`streamingDisplay` configuration object directly instead of separate
variables. This simplifies the monitor layout logic for both Niri and
Hyprland.
Additionally, remove the fragile `sunshineOutputIndex` option in favor
of using the stable connector name for Sunshine's `output_name`. This
prevents issues where numeric monitor indices drift after hotplugging.
The change also includes an explicit encoder list for Sunshine to avoid
probing for AV1 on hardware that does not support it.
