iOS/iPadOS Safari compatibility: replace vh with svh and vw with svw

Description

To improve iOS/iPadOS Safari compatibility, vh units should be replaced with svh and vw with svw, as Mobile Safari handles vh inconsistently due to dynamic browser UI resizing (address bar, toolbars), leading to layout jumps and incorrect viewport calculations. These new units are specifically to solve this problem and are supported for many years in all major borwsers.

Thank you!
