Sway does not pass output scaling to XWayland clients, so XWayland games
on a HiDPI panel render at logical resolution and get upscaled (issue
#45). Add an opt-in xwayland_native_resolution entry flag that drops
sway's output scale to 1.0 for the duration of the activity and restores
it on exit. The HUD compensates with a counter-scale broadcast via a new
HudScaleChanged event so it stays at its usual physical size.

Fixes #45

Scale HUD icons and volume slider with HUD scale factor ... 3eab047b5d

The XWayland HiDPI scaling change in 1314fde left
`gtk4::Image::set_pixel_size(20)` and `Scale::width_request(100)`
unscaled because they are widget properties, not CSS literals reachable
by the per-px stylesheet rewrite. On the kiosk panel at factor 1.5 the
four bar icons and volume slider were visibly undersized.

Move those magic numbers to `BASE_ICON_PIXEL_SIZE` and
`BASE_VOLUME_SLIDER_WIDTH` and extend the scale-change branch of the
500ms timer to update each on factor change. The two icon-name buttons
get explicit child `Image` widgets so their pixel size is reachable;
dynamic icon swaps now go through `Image::set_icon_name(Some(..))` on
the child instead of `Button::set_icon_name(..)`, which would replace
the child entirely.
