fix: set production VITE_API_URL/VITE_WS_URL explicitly in CI build

The Gitea Actions workflow checks out a fresh copy of the repo via
actions/checkout, which never has frontend/.env.local (it's gitignored,
only exists in the manually-maintained /root/realtime-collab clone).
Without it, Vite silently fell back to the localhost dev defaults and
baked a broken API URL into the production bundle — every CI-triggered
build overwrote a working manual build with a broken one.
