fix(home): scale entire continue watching card on desktop hover

[neerajlovecyber]

Summary

Fixes the hover animation on Continue Watching landscape cards so the entire card scales up smoothly (1.05x) and elevates above neighboring cards, consistent with all other desktop catalog cards (NuvioPosterCard, CollectionCard, ContinueWatchingWideCard, etc.).

Previously, .clip(RoundedCornerShape(...)) was chained before .posterCardClickable(...), trapping the hover graphicsLayer scale inside the unscaled card boundaries. As a result, hovering would zoom and crop the inner image rather than scaling the entire card. Moving .posterCardClickable(...) to the start of the modifier chain allows the entire card to expand on hover.

Why

In the desktop Continue Watching row, hovering over landscape cards resulted in the inner artwork zooming in place while the card frame remained stationary. All other cards across the app grow outwards when hovered. Placing .posterCardClickable(...) before .clip() fixes the modifier execution order so the card scales as expected.

Desktop scope

Desktop app (commonMain layout component ContinueWatchingLandscapeCard). Affects Windows, macOS, and Linux desktop builds where desktop hover scaling is enabled. On touch-based mobile devices, desktopPosterHoverScale is a no-op (if (!isDesktop) return this).

Scope boundaries

• Only modifies modifier chaining on ContinueWatchingLandscapeCard in HomeContinueWatchingSection.kt.
• Does not modify any other card components or layouts.
• Does not alter click handling, badge placement, or progress bar logic.

Testing

• Tested on Windows 11 x64 desktop.
• Verified on local build (Nuvio.exe): hovering over Continue Watching landscape cards now smoothly expands the entire card (1.05x) and elevates above adjacent cards.
• Verified click and long-press interactions still trigger properly.
• Confirmed touch interaction on mobile remains unaffected.

Screenshots / Video

Verified on desktop: Continue Watching landscape cards smoothly scale up the whole card container on mouse hover instead of zooming the inner image inside a stationary frame.
