fix(iptv): keep the guide visible on landscape phones

[Saelon600]

Summary

• Adds an explicit compact mini-player layout for touch phones in landscape orientation.
• Places a constrained 16:9 video card beside condensed programme information instead of stacking a full-width player above the guide.
• Hides description/next-programme detail only in compact landscape mode so the category rail and EPG remain visible.
• Leaves phone portrait, tablet, and TV mini-player layouts unchanged.

Why

On short landscape phone screens, the stacked mini-player can consume nearly all available height and push the Live TV guide out of view.
