zebra-report: deploy silent-listener fix + listener-bye-on-bfcache fix

Browse source 
Pulls in two upstream zebra-report commits:

  0ce1339 prefix-match in flushSfuStreams (kills the silent
          fedora-chrome listener: ontrack races peer-joined, cache
          keyed by 16-char streamID prefix, flush's strict-equality
          matcher never resolved short→full, listener heard nothing
          from anyone already in the room).

  5e8cdad send 'bye' on pagehide for listeners even when
          persisted=true (kills the closed-firefox-phone roster
          zombies sitting through the 120s readTimeout window).

Server-side backstop (60s listenerAliveTTL) ships separately in
proxy.unturf.com main; the client fix above stands on its own for
the common bye-arrives case.

Fox 2026-06-06: "rebooting fedora chrome blanka because it never
could hear any speakers for days now".
