On tvOS a Form row is one focusable unit, so the legacy account/source
cards - header, credential fields, and both buttons stacked in a single
row - focused as a whole and every click fired the first button (Remove),
making credentials and Import unreachable.
- Split the tvOS rows into individually focusable rows (info header,
fields, Import, Remove), keeping the card layout on iOS/macOS
- Wrap the tvOS entry points in TVSidebarDetailContainer and drop the
tvOS navigationTitle that rendered as a ghost behind the form
- Present the review screen from the first-launch alert as a
fullScreenCover on tvOS: sheets render as a small transparent card
that cannot fit the sidebar layout (Menu button dismisses the cover)
- Dim disabled TVSettingsButtonStyle buttons
- Widen the row icon frame for tvOS glyph sizes and skip the caption
when it would repeat the host shown as the title
Add a TVSourceRowLabelStyle for consistent icon/text spacing, switch
the Scan Network button to TVFormRowButtonStyle so it matches the
NavigationLink rows, and drop the duplicate navigationTitle in
AddWebDAV/AddSMB views since the title is already shown in the
TVSidebarDetailContainer sidebar.
Remove 32 non-dotted keys (16 unused format specifiers, 16 word keys)
and replace with properly namespaced dotted keys following the existing
convention (common.*, player.*, search.*).
