🐛 Fixed posts list scrolling and missing momentum scroll on all screens in iOS

closes https://github.com/TryGhost/Ghost/issues/9494, refs https://github.com/TryGhost/Ghost/issues/10365
- removed `overflow-y: auto` on posts list to fix the vertical scrolling
- added `overflow-wrap: break-word` so that post previews are forced to wrap for long words such as URLs
- added `-webkit-overflow-scrolling: touch` to the main scrollable pane so that iOS Safari uses momentum scrolling
