fix: resolve content clipping on mobile by moving tab padding to scroll container

Moves dynamic pt-20/pt-40 padding from perspective-container-wrapper (which
shrank the content area) to the inner scroll container via computed style.
Removes spacer divs in CloudFolder, AppDetails, MarketplaceAppDetails.
Reduces excessive bottom padding in Marketplace. Hides Cloud/Network tabs
in CloudFolder detail view. Teleports mobile back buttons to body to escape
CSS transform containing block.
