fix(wasm): resolve browser origin via JSImport, thread-safe model synchronization, and bump to v3.10.0

[spelech]

Summary

This PR addresses silent WebAssembly network failure when accessed over remote or custom URLs, resolves race conditions in model library loading, fixes dynamic engine health indicator dot bindings, and bumps the application version to v3.10.0.

Key Changes

1. Dynamic Origin Resolution via [JSImport]:
   • In LocalLLMServerManager.Web/Program.cs, binds [JSImport("globalThis.getOrigin")] to dynamically inspect window.location.origin upon WASM initialization.
   • Configures MainViewModel.DefaultHttpClient.BaseAddress with the detected browser origin.
2. Centralized HttpHelper Factory:
   • Added LocalLLMServerManager.Shared/Services/HttpHelper.cs to ensure sub-viewmodels (CivitaiSearchViewModel, HuggingFaceSearchViewModel, SettingsViewModel, TelemetryViewModel, AudioStudioViewModel) construct clients with valid BaseAddress values when calling relative API routes in WASM.
3. Thread-Safe Model Loading:
   • Added SemaphoreSlim synchronization to OllamaLibraryViewModel.LoadInstalledModelsAsync to prevent concurrent ObservableCollection race conditions during automatic startup polling.
4. Dynamic Health Dot Data Binding:
   • Replaced static theme brushes in TelemetryHeaderControl.axaml with dynamic color properties (OllamaStatusColor, ForgeStatusColor, ComfyStatusColor).
5. Version Bump to v3.10.0:
   • Synchronized v3.10.0 across all project files, release scripts, installers, documentation, and test assertions.

Verification Pass

• npm run lint passed (0 errors)
• npx tsc --noEmit passed (0 errors)
• dotnet test LocalLLMServerManager.sln passed (311 passed, 1 skipped, 0 failed)
• Playwright WASM browser E2E test passed cleanly
