Fix NavigationPageHandler, StepperHandler, TimePickerHandler from decompiled

NavigationPageHandler:
- Added LoadToolbarIcon() method for PNG/SVG toolbar icons
- Added icon loading in MapToolbarItems()
- Fixed OnVirtualViewPushed to set Title and handle null content
- Fixed animation parameters to match decompiled

StepperHandler:
- Added MapIncrement() and MapIsEnabled() methods
- Added dark theme color support in ConnectHandler

TimePickerHandler:
- Added dark theme color support in ConnectHandler

SkiaPage:
- Added Icon property to SkiaToolbarItem class

Also added Svg.Skia package reference.
