The previous hotfix's disconnect()-on-comm-error path can now fire
during server/brewpi.py's own final best-effort hardware-release
cleanup (finally: block's heater.close()/stirrer.activate(False)),
which runs after the event loop has already stopped - previously
nothing about hardware teardown touched an AttributeChange-tracked
field, so this path was dormant. asyncio.create_task() there raises
RuntimeError: no running event loop, crashing the shutdown sequence.
Adds fire_and_forget() (tasks/task.py) - asyncio.create_task() that
silently drops the message instead of raising when there's no loop to
schedule on - and uses it for the Connected/FirmwareVersion broadcasts.
SudTask.check_connections() also now no-ops entirely without a running
loop, since self.sud.stop() cascades into further unguarded
create_task() calls (on_state_changed, heater_task.shutdown(), ...)
that a stopped loop can't help with anyway.
Reproduced and verified fixed directly against HeaterTask/HeaterHendi
with no event loop running (mirrors the exact server/brewpi.py
shutdown-time call path that crashed on the brewpi Pi).

SudLogTask reuses ServerLogTask's sample format but only records while
a Sud run is active: starts on Play (fresh start only, not a Pause
resume) and writes logs/log_{date_time}_{sud_name}.log on Stop or
natural completion.

SudLogTask is removed; ServerLogTask now covers the full server session
and gains PlantParams tracking (log_plant_params callback wired from
SudTask.set_on_plant_params) so step transitions are still captured in
the log.

Adds ServerLogTask (tasks/server_log.py) which records temp/power samples
from startup to shutdown regardless of Sud state, in the same Name/Samples
JSON format as SudLogTask so analyze_log.py and replay_sim.py can consume
it directly. The file is written on graceful exit (Ctrl-C) from brewpi.py's
finally block, just before the heater is closed.

Its brewpi.mat output had no consumer - the GUI never subscribed to the
'Tracer' channel, and SudLogTask's run-scoped JSON logs now cover the same
sensor/heater/tc data for actual analysis. Drop the task, its DT_TASK_TRACER
interval, and the wiring in server/brewpi.py.

Add SudLogTask: starts a fresh in-memory buffer the moment a run actually
starts (Sud.state leaves IDLE/DONE) and writes it out whole the moment it
ends (DONE, or aborted via Stop) - log_<date>T<time>_<sud-name>.json holds
the same six signals the GUI's Automatic tab plots live (temp/rate ist+soll,
power set+eff) with per-sample timestamps; forecast_<date>T<time>_<sud-name>.json
holds the final, most-corrected forecast curve from the same run, sharing
the run's date-time token so the two pair up.

brewpi.py had a dead -m/--model CLI arg and sude/*.json schedules were
pure data with no code to drive them, despite the README documenting
them as if they were already wired up.
Add components/sud.py's Sud, which loads a sude/*.json schedule and
steps through its Rasten (ramp -> hold -> optional wait-for-user ->
next rest), and tasks/sud.py's SudTask, which drives the temperature
controller's theta_soll/heatrate_soll from the current rest and
switches the stirrer between continuous (ramping) and intermittent
(holding, via stirrSpeedRast/stirrDutyRast/stirrCycleTime) operation.
Exposes progress on a new "Sud" WebSocket channel and accepts
Start/Confirm commands. Enabled via a new optional top-level "sud"
config key (see config.json.templ/.sim).
"Reached target" is detected via abs(theta_ist - theta_soll_set) <
tolerance rather than tc.state == HOLD, since the latter can still
read HOLD left over from the previous rest for one tick after a new
target is pushed (tc.state only updates on the controller's own,
independently-scheduled process() tick).
