Subject: [PATCH] perf(dashboard): reduce first-screen load (lazy-load
 VAD/Monaco/i18n/ApexCharts, gzip responses) (#10413)

* perf(dashboard): lazy-load VAD dependencies on demand

Load onnxruntime-web and vad-web via dynamic script injection when the
VAD initializes instead of render-blocking script tags in index.html,
so they no longer delay the first paint on every page load.

* perf(dashboard): shrink first-screen bundle and gzip responses

- Lazy-load Monaco Editor (~3.3 MB) via an async wrapper component
  instead of importing it in main.ts; the editor bundle now loads only
  when an editor is first mounted.
- Load i18n locale data on demand: each language becomes its own async
  chunk instead of bundling all four locales (~1.4 MB of JSON) into the
  entry.
- Register vue3-apexcharts locally in StatsPage instead of globally in
  main.ts, moving ~470 KB out of the entry chunk.
- Add Starlette GZipMiddleware to the dashboard ASGI app so static
  assets and API responses are compressed (SSE is excluded by default).

Entry chunk: 4.5 MB -> 648 KB (gzip: 1.25 MB -> 210 KB).
