Bump fc-chat image to localhost/fc-chat-web:v20260617-chatfix-54fd549, built
for arm64 on GX10 from Chat master 54fd549 + Common 0a4174d:
- OperatorRouteRedirect bounces ANY unauthorized path to sign-in (was: only
operator/ops-chat prefixes, so /tickets sat on "Redirecting..." forever)
- FcAiChat send button stays clickable as Cancel while generating + closes
the reconnect-recovery gap so it re-enables after a circuit drop
