Subject: [PATCH] fix: adjust applet icon smoothing on rotation

1. Replace the static contentItem.smooth = false assignment with a
Qt.binding in Component.onCompleted
2. Bind smooth to Math.round(contentItem.rotation) % 90 !== 0, enabling
smoothing only when rotation is not a multiple of 90 degrees
3. Keep smoothing disabled at 0, 90, 180, and 270 degree orientations to
preserve crisp, pixel-aligned rendering
4. Enable smoothing for arbitrary rotation angles to reduce jagged edges
on rotated applet icons

Log: Updated applet icon smoothing behavior to enable anti-aliasing only
for non-90-degree rotations

Influence:
1. Verify applet icons render sharply when rotation is exactly 0, 90,
180, or 270 degrees
2. Verify applet icons render smoothly without jagged edges at arbitrary
rotation angles such as 45 or 30 degrees
3. Test rotation animations and transitions to ensure smoothing toggles
without visual glitches
4. Confirm no QML binding errors or warnings appear in the console
5. Check behavior
