Ken Van Hoeylandt d6b1d15e56 Various improvements (#614)
- Auto-select widgets in Launcher and apps with toolbars on devices without touch.
- Improved USB HID input reliability, cleanup
- Updated PSRAM settings to improve boot stability on supported devices.
- Prevented duplicate Wi-Fi event subscriptions during screen rebuilds.
- Updated docs
- Fixes in WifiManage and WifiConnect
- Reduced main task stack size
- Moved USB HID stack size to PSRAM when available
- app_manager_find_manifest() now returns a copy instead of a pointer
