Resolution dropdown, list-focus preservation, unified dark theme, startup logging, and memory map

Browse Source 
- Bottom-bar resolution dropdown (1080p60/1080p30/720p60/480p30) with tooltip
  on finding upload bandwidth; disabled while live; no in-app speed test
- FocusPreservingListBox keeps selection/focus coherent when a selected
  scene/source is deleted (skip hidden scenes; leave list when empty)
- Themes/Controls.xaml: single dark-theme dictionary merged once in App.xaml;
  custom ComboBox template fixes SelectionBoxItem rendering; GoLiveWindow and
  ReuseImageDialog consolidated onto shared styles
- AppLog file logger + AppDomain/Dispatcher exception hooks; checkpointed
  MainWindow/VM/dialog constructors (caught MenuItemRole.Separator XAML crash)
- Memory map: schema.md conventions, per-directory index.md, updated ai.md/
  TASKS.md/README.md (OAuth creds real; token persistence still pending)

### Key patterns
@@ -32,16 +37,18 @@ C# / WPF (.NET 8) following MVVM:
- ViewModels are constructed in XAML (`<vm:MainViewModel/>` as DataContext)
- Services are currently instantiated in MainViewModel's constructor — no DI container yet
- Layout persists to SQLite (`Microsoft.Data.Sqlite`); scenes/sources/asset bytes stored in the DB, asset identity is a SHA-256 content hash (1:M reuse, no file paths — assets are always available)
- Theming: all custom styles live in `Themes/Controls.xaml`, merged in `App.xaml` — never duplicate styles per-window (dialog duplicates were consolidated into this dictionary)
- Resolution tiers (bottom bar): 1080p60@8 → 1080p30@8 → 720p60@6 → 480p30@2.5 Mbps; default = first. A **tooltip** explains finding upload bandwidth — an in-app speed test was deliberately dropped (unreliable)
- Crash diagnosis: `AppLog` writes startup checkpoints to `%APPDATA%\ytLlive\startup.log`; `App.xaml.cs` logs `DispatcherUnhandledException`/`AppDomain.UnhandledException`. When WPF won't run from WSL, this log is how you find the failure (it caught the `MenuItemRole.Separator` XAML crash and the ComboBox SelectionBoxItem bug)
### Current limitations / TODOs
- `OAuthCredentials.ClientId` / `ClientSecret` in `Helpers/OAuthCredentials.cs` are empty — the app
owner fills them in once (developer task, baked into the binary; creators never configure anything)
- `Helpers/OAuthCredentials.cs` now contains the real ClientId/ClientSecret — auth service is implemented, but **tokens still don't persist** (Windows DPAPI planned; account UI in the GoLive dialog is simulated)
- `GoLiveViewModel.SignIn`/`ChangeAccount` removed — Connect (OAuth) is the only entry to streaming
- No token persistence yet (Windows DPAPI planned) — scene/source/asset layout *does* persist (SQLite)
- Scene/source/asset layout *does* persist (SQLite); token persistence does not (yet)
- `YouTubeStreamService` uses hardcoded `1080p`/`60fps` and per-broadcast streams — must switch to the v3 `variable` reusable stream
- No capture/encoding/RTMP yet
- Stream config (title/description/visibility/quality) still in-memory
- `StreamConfig` defaults (`TargetBitrate=6000`, `Resolution="1920x1080"`) are stale — the live dropdown drives `StreamHealth.CurrentBitrate`/`FPS` instead
