fix(pi-family): per-tab client_id for the QEMU-Linux WebSocket 

With the bare boardId as client_id, two tabs (or two users) on the same
example shared one QEMU instance: serial output went to whichever socket
connected last, keystrokes interleaved and one tab's stop killed the
other's guest. Suffix the tab session id so each tab gets its own
instance (stopped on its own disconnect, like the ESP32 workers).
