Viktor's 'VNC stuck loading forever' (remote network): noVNC 1.3 is
unbundled and fetches ~60 ES modules in parallel on page open; the shared
Traefik rate-limit (average 10, burst 50) 429s the tail and noVNC's
loader waits on the missing modules indefinitely (reproduced: 38x429 in
a 90-request burst through the ingress). Adds a dedicated 50/300
android-emulator-rate-limit middleware (actualbudget/immich pattern) and
opts both emulator ingresses out of the shared limiter.
