fix(home): restore poster and catalog skeletons with correct TV/mobile title visibility

[Himanth-reddy]

Restores clean dynamic poster and catalog skeletons in the home feed. Reverts data-layer workarounds and implements conditional title rendering for TV poster lists where card titles are disabled.

The PR removes the Smooth Scrolling row/action, but tvGeneralRowsForSection("appearance") still includes row id 36. On TV/D-pad this can create an invisible/unhandled focus stop in Appearance settings.

Please either:

1. fully keep Smooth Scrolling: restore the row, Enter action, and make Home respect smoothScrolling; or
2. fully remove it: remove row 36 from tvGeneralRowsForSection, remove the unused callback/state plumbing from SettingsScreen, and make the PR description clear that Smooth Scrolling is being removed.

After that, I think this is okay.

Why does smooth scrolling need to be removed?

[Himanth-reddy]

I originally mistakenly thought that the "Smooth Scrolling" toggle was doing nothing because even with the toggle turned off, the list still scrolled smoothly. But after checking it was working so i reverted the commits related to smooth scrolling

Sorry for making you confused
