fix(mac): scroll the account detail pane so tall content doesn't clip

The detail pane is pinned to a fixed-height container, so an iCloud account —
whose sync controls make the form taller — clipped the Hide Read Articles
button at the bottom with no way to reach it. Wrap the form in a ScrollView;
.scrollBounceBehavior(.basedOnSize) avoids rubber-banding when the content
already fits (every non-iCloud account).
