The module used to proxy each browser's transcript stream to ProdCom one
to one, so N screens meant N upstream connections and N history reads.
It now follows ProdCom once: it keeps the channel list, the groups and
the last 300 entries, and gives every browser a snapshot on connect
(`state`) plus each changed entry as it happens (`entry`), with `clear`
and `status` frames as the link changes. Reconnects back off from 2 s to
15 s, re-read the lists and history, and re-send the snapshot. The tile
no longer loads anything itself; the admin readout says how many channels
and entries the server holds. The /prodcom/* proxy is gone.
