Adds StatusError flags for the STATUS register and get_status_errors();
go() now reports if a fail-safe (safe-start violation or other error)
persists after GO instead of failing silently. _on_process uses the
same decoding to log any active error and only auto-recovers on a
safe-start violation, rather than the old narrow status & limit_status
heuristic.

Heater and Stirrer can be real serial hardware (hendi, Pololu1376), but
there was no connection concept at all - the constructors opened the
port and crashed the whole server if the device was missing, with no
way to see connection status or firmware version and no way to
reconnect without a restart.
Adds an observable Connectable mixin (components/connectable.py) shared
by AHeater/AStirrer; real devices defer opening the serial port to an
explicit connect(), auto-connect on server startup, and surface
Connected/FirmwareVersion/Simulated plus manual Connect/Disconnect over
the web GUI. Heating/stirring and Sud Start are all gated on connection
state, and a disconnect mid-brew force-stops the run via the same path
as a manual Stop.
