Adds an option in Appearance settings to use different accent colors
in light and dark mode, with a toggle to keep a single shared color
(the default, preserving existing behavior).
- New synced settings keys: accentColorDark, customAccentColorDark,
useSeparateDarkAccentColor; dark values fall back to the light
selection until explicitly set, so no migration is needed
- resolvedAccentColor returns a dynamic platform color (UIColor trait
provider / NSColor appearance provider) when the toggle is on, so
the root tint and all direct readers adapt to light/dark
automatically without consumer changes
- Accent Color section shows two stacked preset+custom grids with
Light/Dark headers when enabled, extracted into AccentColorGrid;
CustomAccentColorButton now takes bindings so the macOS color panel
edits whichever target was last opened
- New DarkAccentColorTests covering sync contract, default-off state,
fallbacks, and toggle-off resolution

Add a Custom swatch to the appearance settings accent color grid,
backed by a hex value stored in settings (synced via iCloud like the
rest). iOS uses the native ColorPicker wheel; macOS uses a circular
swatch that opens NSColorPanel, since the SwiftUI color well looks out
of place among the circles. All accent consumers now read the resolved
color through SettingsManager.resolvedAccentColor.
The indigo preset is retired from the grid but kept in the enum, so
users who selected it keep their color until they pick another one.

Replace the three-way macOS Player Mode picker (Separate Window /
Floating Window / Inline) with a single 'Play in a separate window'
toggle in Playback settings, and move the always-on-top choice to a
pin button in the player's top bar (window mode only).
Floating was really a transient window property (NSWindow.level), not
a peer of the window/inline structural choice — so it belongs on a live
control, not in Settings. The pin state persists across sessions.
- Replace MacPlayerMode enum with macPlayerSeparateWindow /
macPlayerFloating bool settings
- Branch runtime presentation and window level off the two bools
- Add pin.fill/pin toggle to MacOSPlayerControlsView top bar
- Update localization; drop obsolete playerMode strings and enum tests
