[Client] Show horizontal art for plane and siege cards in the profile banner (#7118) (#7250)

Use the landscape orientation flag to rotate sideways-layout card art
upright before cropping, so planes/sieges show their horizontal art as
the server profile banner card instead of a rotated full card.

- Curve cropCardArt around the card's landscapeOrientation flag with
  landscape-specific art margins (mirrors CardInfoPictureWidget)
- Add shared CardArtUtils::rotateSidewaysLayoutArt helper and apply it
  to the playmat (game render and settings preview) and card info widget,
  replacing three duplicate 90-degree rotation blocks
