android-emulator: api36-v7 — noVNC defaults: scaled view, autoconnect, reconnect

Viktor's screen rendered unscaled on a bare /vnc.html. The entrypoint
now writes /usr/share/novnc/defaults.json (resize=scale, autoconnect,
reconnect with 2s delay, shared) so every load behaves right without URL
params, and viewers self-heal across pod restarts/wakes. Already applied
live to the running pod; this makes it survive the next wake.
