Configurable Display Screens & Rotation Control in AxeOS

[0fficerDoggo]

It would be useful if AxeOS allowed users to configure which screens are shown on the Bitaxe display and how they are displayed. Users should be able to enable or disable individual screens and adjust the rotation speed or disable rotation entirely, allowing a single screen (for example, the statistics screen) to remain visible at all times. For safety and troubleshooting, the stratum host could be shown automatically for a short period after reboot (e.g. 15 seconds), while remaining optional or disabled during normal uptime. This would improve usability without removing important diagnostic information.

Be aware that some models of the used OLEDs are prone to burn-in, especially the blue ones. Having a single screen makes this worse.
