Extend SettingsFormSection to accept a @ViewBuilder footer for sections
with dynamic multi-line content (last background refresh, orphaned
files status). Move trailing button accessories (size, progress) out of
button labels so buttons size to their content on macOS.
Includes SponsorBlock, Return YouTube Dislike, and DeArrow sub-screens.
Extend SettingsNavigationRow with an optional trailing content slot so
rows can show enabled/disabled status next to the chevron.
Add SettingsNavigationRow helper that renders destination-pushing rows
as plain list rows with a trailing chevron on macOS, and drop the top
divider in headerless sections so they don't render a stray rule.
Add shared SettingsFormContainer/SettingsFormSection helpers that mirror
the Sources screen styling (uppercase subheadline headers, divider-
bracketed cards, ScrollView + LazyVStack) on macOS while keeping the
standard Form/Section layout on iOS and tvOS.
Convert PlaybackSettingsView and SubtitlesSettingsView to the new
helpers, wrap the macOS Settings detail pane in a NavigationStack so
NavigationLink pushes (Subtitles Appearance) render in the detail
column, fold the macOS-only Player Mode + Auto-resize player controls
into the Behavior section, and drop the unused queue footer.
