fix(web): clamp wgpu surface to CSS pixels on HiDPI to prevent wasm panic

Browse Source

Root cause: fit_canvas_to_parent requests a wgpu surface sized in
physical pixels (CSS pixels × devicePixelRatio). On HiDPI displays
(DPR ≈ 2) the physical size (e.g. 2612×1469) exceeds WebGL2's per-
dimension texture limit of 2048, triggering a wgpu validation panic
that kills the WASM thread immediately on the first window resize.

Fix: add `resolution: WindowResolution::default().with_scale_factor_override(1.0)`
to the primary window so Bevy uses CSS/logical pixels as the surface
dimensions. For a 1306×734 CSS viewport this keeps the framebuffer well
within 2048 regardless of devicePixelRatio.

Also remove the temporary [drag] console logging added in the previous
commit — the panic was causing drag to never run, not a hit-test bug.
