kbx81 88402743d5 [serial_proxy] Enforce session scoping and RAW inertness for the port mode
Address review findings:
- Only the live subscriber may set the mode, so a mode set by a client
  that never subscribes cannot persist past its session
- With a subscriber attached, the mode alone decides whether the tap is
  served; tap_needs_port() bypasses it only while the port is unheld,
  and write_from_tap() is gated the same way, so RAW is inert by code
- The explicit UNSUBSCRIBE path keeps the loop alive for a tap that
  still needs the port, mirroring the disconnect path in loop()
- Mode values from the wire are validated; unknown values are refused
  with INVALID_ARGUMENT instead of stored and acknowledged OK
- Add a test variant that defines USE_SERIAL_PROXY_TAP so the tap code
  paths compile in a real build
