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.

Legacy v1 instances without an account had no import path after the
switch to explicit account review. Surface them in a separate "Sources"
section of the legacy import view where they can be added with a single
tap (no sign-in) or removed, mirroring the accounts flow. Instances tied
to an account stay in the Accounts section and are not duplicated.
Detection now gates the entry points and first-launch prompt on any
legacy data (accounts or sources), not accounts alone.
Add macOS-only minimum frame sizing to sheets that wrap a
NavigationStack/Form without intrinsic size, so they render properly
instead of collapsing to just the toolbar. Affects Customize Home,
subscription/channel view options, playlist create/edit, search
filters, media browser options, instance picker, log filters, preset
editor, and legacy data import result.
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.
