fix(arima): let an explicit biasadj override the reused model `Arima(..., model=m)` inherited `biasadj` from `m` unconditionally, and since every model fitted with a Box-Cox transformation now carries a "biasadj" key, the caller's value could never win: `Arima(y, model=m, biasadj=True)` on an `m` fitted with `biasadj=False` returned medians instead of bias-adjusted means. `biasadj` now defaults to None and is only taken from the model when the caller didn't ask for one, mirroring the `blambda is None` guard on the line above and the sentinel `forecast_arima` already uses. Also raise the Guerrero lower bound to 0 when the series isn't strictly positive, as `forecast::BoxCox.lambda` does, so the search stays where the transformation is defined. coreforecast doesn't currently return a negative lambda for such a series, so the bound is pinned at the call.

fix: validate level support for models without prediction intervals Twelve models set `only_conformal_intervals = True` but `StatsForecast` never checked it. Passing `level` to one of them without configuring `prediction_intervals` either raised a generic `Exception` in the middle of the run or, when a `fallback_model` was set, silently returned the fallback's intervals under the original model's name. `_validate_level_support` now runs from `_parse_X_level`, so `predict`, `fit_predict`, `forecast` and `cross_validation` all raise a `ValueError` up front that names the offending models and how to fix it. Closes #237
