Firefox Hotfix release & Browser Cache fix

🐛 Bug Fixes

• web: Fixed Firefox hanging on Service Worker-streamed downloads for files >= 2 GiB. Firefox has a long-standing signed 32-bit integer overflow in its internal download pipeline that triggers when Content-Length is >= 2^31 bytes, causing the download manager to stall or cancel at the end. The Content-Length header is now omitted for files >= 2 GiB so Firefox falls back to reading until EOF. Files below 2 GiB and all other browsers are unaffected. Thanks @Dominion0815
• web: Fixed the Service Worker download progress not reaching 100% and the UI not transitioning to "done" after the download completes. The dl-done broadcast was fire-and-forget - Firefox terminates the SW as soon as waitUntil resolves, abandoning the still-pending clients.matchAll() call before the message is delivered. All completion broadcasts are now awaited before streamDone() is called.

🎨 Improvements

• server: The SPA entry point (index.html) is now served with Cache-Control: no-cache, must-revalidate. This prevents browsers and reverse proxies (e.g. Traefik with a caching middleware) from serving a stale index.html after a deployment. Without this, a cached old index.html referencing a previous JS bundle hash would cause 500 errors for the JS assets because the old filenames no longer exist on the new server.
