Fix paywall dialog composable sizing issues (#1556)

### Description
As I was testing #1551, I noticed that the dialog size wasn't correct.
The width of the device sometimes was `MEDIUM` on a phone, causing it to
present the dialog in a narrowed version. After more testing, I noticed
that it was always one of the dimensions that were not `COMPACT` on my
emulator, so I decided to check both. If one of the dimensions is
`COMPACT`, we would present the dialog as full screen.
