1. Remove all rvote/proposals fetching from rstack-user-dashboard.
rApp-specific data (proposals) should stay within the rVote module,
not leak into the space-level dashboard.
2. Fix url.protocol in bare-domain redirects — TLS is terminated by
Cloudflare/Traefik so url.protocol is always http: internally.
Use https: for production domains.
3. Rewrite /{space}/api/... paths internally on bare domain instead
of redirecting to subdomain (avoids CORS + mixed content issues).
