    Fix blurry text in HiDPI offscreen-rendered widgets
    
    Fix blurry text on HiDPI/Retina displays in custom GnuCash widgets
    that render into offscreen Cairo image surfaces.
    
    This updates the register header and dense calendar widgets to
    create scale-aware backing surfaces using the GTK widget scale
    factor and `cairo_surface_set_device_scale()`.
    
    - Register column headers
    - Scheduled transaction dense calendar
    
    Tested locally on macOS Apple Silicon with a native arm64 build.
    
    Confirmed that:
    - register header text now renders crisply
    - scheduled transaction dense calendar text now renders crisply
