Replace the quality dropdown with a range slider in the settings
panel. The slider goes from Auto (green) through Opus 24k, Opus 6k
(yellow), Codec2 3.2k (orange) to Codec2 1.2k (dark red). The
track uses a green-to-red gradient and the label color updates
to match the selected level. Removed the quality dropdown from
the connect screen — quality is now settings-only.
