refactor: move pot hardware params and pid_type out of per-brew docs

Pot hardware constants (mass, material, L, Td) moved from sude/*.json
to config.json's Pot section; Sud/SudForecastEstimator accept pot_config
as baseline, per-brew pot sections may still override. Controller key
removed; pid_type moved into TempCtrl.
