Sud now parses top-level L/Td fields from sude/*.json (defaulting to 0.2/30,
matching the old hardcoded server constants), and derive_plant_params()
returns them alongside M/C - constant for the whole brew, unlike M/C which
vary per step with grain/water mass. All sude/*.json docs gain explicit
L/Td fields.
Callers (tasks/sud.py, SudForecastEstimator, demo_sud.py) switch from the
narrow set_thermal_params(M, C)/set_model_params(M, C) to the full
set_plant_params(params)/set_model_plant_params(params), since
derive_plant_params() now always returns all four keys; both narrow setters
are removed as dead code.
Caught along the way: Pot.set_plant_params() unconditionally rebuilt the
Delay ring buffer, which was harmless when only ever called once at
construction - but now running on every Sud step change, it was wiping
in-flight delayed power at each step boundary. Fixed to only rebuild when
Td actually changes; verified this restores the exact original forecast
result for sud_0010.json.

TempController(Smith).__init__ no longer takes model_params/theta_amb -
set_model_plant_params() and the existing set_ambient_temperature() must be
called instead (mirrors components/plant/pot.py's own Pot constructor
refactor). temp_controller.py's now-pointless model_params/theta_amb
constructor placeholders (kept only for "compatibility" with Smith) are
dropped too.
Both TempController variants now raise a clear RuntimeError from process()
itself if set_params() wasn't called, instead of letting it surface deep
inside Pid.process() as an opaque "'NoneType' object is not subscriptable".
Smith additionally checks its internal models via Pot.is_configured() (new)
and raises if set_model_plant_params()/set_ambient_temperature() weren't
called either.

Pot.__init__ now only takes dt; set_plant_params() and set_ambient_temperature()
must be called before process(), which now raises RuntimeError if either is
missing instead of silently computing on whatever the constructor happened to
default to. set_ambient_temperature() only seeds the plant's starting
temperature the first time it's called, so changing ambient mid-run still
can't clobber an in-progress simulated temperature. Updates all callers
(server/brewpi.py, TempController(Smith)'s two internal models,
SudForecastEstimator, and the plant/pid/sud demo scripts) to call the setters
right after construction.

grain_mass and water_mass now live on each step (defaulted from
default.step) instead of being fixed for the whole brew, since both
change over a mash (malt going in, water boiling off).
Sud.derive_plant_params() takes them as arguments so it can be
recomputed per step; the demo re-applies the resulting M/C to both the
real plant and the controller's Smith-predictor model on every step
change via the new Pot.set_thermal_params()/
TempController.set_model_params().

[Pot] - removed the gain (efficiency) factor and the separate
"theta" initial-temperature param; Pot now starts at theta_amb and
set_power()/get_power() operate on p_in directly. Added
set_ambient_temperature() for live ambient updates. Dropped the
now-unused "theta"/"gain" keys from Model/Plant in config.json.sim
and config.json.templ (also fixes a JSON syntax error in
config.json.templ: trailing commas left over after removing "gain"
made Model/Plant fail to parse).
[Sensor] - fix missing space in TempSensorSim.temperature()'s
offset/variance expression (cosmetic, no behavior change).

The unconditional p_loss/theta_amb/temp prints (left over from the
heat-loss-units fix) ran every tick, spamming stdout in both the
server and every demo script. Drop them and check off the matching
TODO.md item.

tc_constants.py only held States and DEFAULT_THRESHOLDS, both used
exclusively by temp_controller_base.py and its subclasses; fold them
into temp_controller_base.py directly and drop the now-empty module.
Also drop heat_diffusion.py, unused since pot.py switched to the
delay-line model, and the matching dead import in pot.py.

[brewpi] - drop trace vars for the dtheta_ist_* attributes removed
when temp_controller_smith.py dropped Kalman filtering
[Pot] - drop unused kn field (never read since the noise-injection
code that used it was dropped)
[GUI] - default WS connection to ws://localhost:8765
