The NavigationStack-level background wasn't enough: macOS draws its own
translucent material behind pushed navigation pages, and Form/List
containers draw a translucent scroll background on top of anything
placed behind them, so several pages kept the wallpaper-tinted look.
Bake the opaque background into SettingsFormContainer (covers all pages
built on it, pushed or not) and add opaqueSettingsFormBackground(),
which hides the container's scroll background before applying the
opaque one, to every macOS-reachable Form/List settings page: player
controls and its sub-editors, sidebar settings, edit source, legacy
data import, subscription/playlist import, customize home and its
shortcut style page, and the log viewer. Contributors, translators and
the remote control device page get the plain opaque background.

Buttons in the section, mini player, and pill editors can now be
removed via long-press/right-click context menu instead of only
swipe-to-delete. This also gives macOS a delete affordance in the
section editor, which previously had none.
Render the macOS control bar button row and top bar from the active
preset's sections via a new MacOSControlsSectionRenderer, replacing the
hardcoded QuickTime-style rows in MacOSControlBar. Add a keepOnTop
button type and macOS-specific button availability lists, and adapt the
player controls settings editors (preset editor, section editor, button
configuration) for macOS.
Also apply the preset font style to the control bar time labels, and
update the built-in macOS Default preset order (queue before transport,
fullscreen at the end), bumping builtInPresetsVersion to 7.
On tvOS, ContentUnavailableView inside a Group doesn't expand to fill
available space — it sizes to content and aligns top-leading. Add
.frame(maxWidth: .infinity, maxHeight: .infinity) to all instances
so they center correctly in their parent containers.
