Phase 2 of the player panels redesign:
- New "Details Panel" screen in Player Controls settings: page
reorder/enable list with per-page editor (info element toggles),
and a default panel visibility picker (hidden/visible/remember).
- PlayerControlsSettingsViewModel gains panelSettings bindings with
the usual debounced-save flow; the last enabled page cannot be
disabled.
- Built-in presets bumped to v9 with explicit default panelSettings.
- The preset's default visibility now drives the wide-layout panel
on player open and on entering landscape, replacing the hard
hidden resets; "remember" restores the new detailsPanelLastVisible
setting recorded on user toggles. Applied once per expanded player
session (flag on NavigationCoordinator survives re-mounts).
- WideScreenPlayerLayout picks up external visibility writes so the
async-loaded default reaches the mounted layout.
- Unit tests for PanelSettings Codable compatibility (round-trip,
old JSON, unknown page types/discriminators/enum values); removed
stale PlayerInfoTab tests left from Phase 1.
Phase 0 of the panels redesign, extraction only, no behavior changes:
- Unify comments loading on PlayerState: loadComments/loadMoreComments
become the single loader, used by both the player sheet preload and
the comments overlay (which previously had its own duplicate copy).
- Extract PanelResizeGrabber from FloatingDetailsPanel into the new
Views/Player/Panels/ directory.
- Extract the shared queue list from QueueManagementSheet into
QueueListView plus QueuePlaybackActions, reused by the tvOS panel.
- Remove the no-op wideLayoutPanelAlignment accessor from the settings
view model; the player reads the panel side from SettingsManager, so
the preset field was dead. The Codable field stays so old presets
decode.
