Audio input + visual fixes - Cap

Audio inputs with high sample rates (>48khz) are now opened with the highest available sample rate supported by the encoder. This should fix issues that have been reported with Macbook Pro mics and some high-end audio interfaces.
Sample rate selection now orders the options from highest to lowest, as opposed to randomly
Editing the cursor size was accidentally enabled, it's now disabled but will be coming back soon
Color inputs now look good in dark mode
