Each log_*.json now carries a "Config" key (the full server config) and
a "PlantParams" list of {t, params} entries — one per step transition —
so offline analysis tools have the PID gains and plant model that were
active at every point of the run without having to cross-reference a
separate config file.

Reanchoring used to only happen when a user confirmed a WAIT_USER
step, so anything the schedule advanced through on its own (a ramp
reaching target, a hold timing out) left the forecast showing a
stale, increasingly wrong prediction once reality diverged from it.
_reanchor_forecast() now fires from on_step_changed() on every real
transition, splicing in a fresh simulation anchored at the real
current temperature/elapsed time instead.
Also fixes two bugs surfaced while testing that change:
- estimate()'s early-return for an empty/not-yet-loaded schedule still
returned the old 4-tuple shape, crashing every connection before a
Sud was ever Loaded.
- send_forecast() and _reanchor_forecast() can run concurrently (e.g.
a fresh Start triggers both at once), and whichever resumed second
after its own worker-thread simulation would blindly splice its tail
onto whatever the other had already written, producing a spurious
connecting line across the plot. Both now carry a generation counter
and discard their result if a newer call has since committed.

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.
