chore: retire legacy oil prediction pipeline
Removes everything that was made redundant by the new forecasting stack. Per docs/superpowers/specs/2026-05-01-prediction-rebuild-design.md, this was the cleanup planned at the end of Phase 4. Deleted services and code: - App\Services\Prediction\Signals\* (the old six-signal aggregator — trend, supermarket, day-of-week, brand-behaviour, stickiness, regional-momentum, oil — replaced by RidgeRegressionModel). - App\Services\NationalFuelPredictionService (the post-Phase-4 thin shim; StationSearchService now depends on WeeklyForecastService directly, set up in the previous commit). - App\Services\LlmPrediction\* (AbstractLlmPredictionProvider plus the four provider implementations — Anthropic, OpenAI, Gemini, and the OilPredictionProvider router. Replaced by LlmOverlayService). - App\Services\BrentPricePredictor and App\Services\Ewma. The Ewma helper had no callers left after BrentPricePredictor went. - App\Models\PricePrediction and its factory. - App\Console\Commands\PredictOilPrices (the oil:predict command). - App\Filament\Resources\OilPredictionResource and its Pages. Schema and dashboard: - Drop the price_predictions table via a new migration. - Repoint the Filament StatsOverviewWidget tile from PricePrediction to WeeklyForecast so the dashboard reflects the new pipeline. - Remove the OilPredictionProvider binding from AppServiceProvider. Test cleanup: - Delete tests for every retired service. - Update StatsOverviewWidgetTest to seed weekly_forecasts instead of price_predictions.
