Cache-Control Fixes for Stale Content and Traefik Caching

server: Changed Cache-Control for index.html and download-sw.js from no-cache, must-revalidate to no-store. no-cache permits storing the response and requires proxy revalidation via ETag or Last-Modified headers, which SkySend does not set - causing Traefik's caching middleware to fall back to its own TTL and serve stale HTML after a deployment. no-store is unconditional and prevents any proxy from storing the response, eliminating the need for a Traefik restart after updates.
server: Added a global Cache-Control: no-store middleware to all /api/* routes. Previously only the successful download stream response carried this header. Error responses from any API endpoint (e.g. a transient 500 from the download route) had no cache directive, allowing Traefik to cache them. A single cached error response caused all subsequent requests to the same URL to receive the cached error until the proxy was restarted.
