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.

Adds `label()` methods to TrendDirection and PredictionSource enums for cleaner display. Fixes mixed tab/space indentation in StatsOverviewWidget. Links all stats cards to their respective Filament resources (searches, stations, oil-predictions, api-logs). Documents BrentPriceChartWidget's manual registration.
Adds complete API reference (api-reference.md) covering all endpoints: /api/stations (nearby search with postcode/lat+lng), /api/stats/searches (aggregated search stats), /api/prediction (7-day price forecast with multi-signal breakdown), and auth routes (register/login/logout/me). Includes request/response examples, error shapes, fuel type aliases, and signal structure details. Also removes unused AccountWidget from admin panel, disables BrentPriceChartWidget discovery, and adds searches stat to StatsOverviewWidget.

Extends NearbyStationsRequest to accept `postcode` (full or outcode) as an alternative to lat/lng. PostcodeService resolves it via postcodes.io and falls through to coordinates. Also adds SearchResource to the Filament admin panel for viewing logged search activity with fuel type filter and price/distance stats columns. Includes SQLite GREATEST/LEAST function polyfills in AppServiceProvider for test compatibility.
