feat: add Filament admin panel with migrations and design spec

- Add AdminPanelProvider mounting panel at `/admin` with `is_admin` auth guard
- Add `is_admin` boolean column to users table
- Add brent_prices and price_predictions tables with appropriate indexes
- Add comprehensive admin design spec covering resources, dashboard, navigation, and build order
- Configure default panel with amber primary color and standard middleware stack
- Add compiled Filament assets (actions.js, app.css)

+- Response must be JSON: `{"direction": "rising|falling|flat", "confidence": 0-85, "reasoning": "..."}`
+- Model sometimes wraps JSON in markdown code fences — these are stripped before `json_decode`
+- Confidence is capped at 85 regardless of what the model returns
+- On any failure (API error, malformed JSON, invalid direction) → falls back to EWMA silently
+- Result stored in `price_predictions` table with `source = 'llm'`

+**EWMA fallback (`OilPriceService::generateEwmaPrediction()`):**
+- Compares 3-day EWMA vs 7-day EWMA on chronological Brent price data
+- Threshold: ±1.5% change → rising/falling; below → flat
+- Confidence capped at 65 (simpler model)
+- Used when: no `ANTHROPIC_API_KEY` set, or LLM call fails
+- Result stored in `price_predictions` table with `source = 'ewma'`

+# Filament Admin Panel — Design Spec
+
+**Date:** 2026-04-04  
+**Stack:** Laravel 11, Filament v5, Livewire v4  
+**Scope:** Admin panel for FuelAlert — internal tooling only, no user-facing exposure
+
+---
+
+## 1. Access & Auth
+
+- Filament panel mounted at `/admin`
+- Protected by `is_admin` boolean on `users` table
+- Migration adds `is_admin TINYINT(1) DEFAULT 0` to `users`
+- `AdminPanelProvider` uses `->authGuard('web')` (same guard as the main app — no separate admin users table)
+- `canAccessPanel()` check: `$user->is_admin === true`
+- `uovidiu@sent.com` seeded as admin via a dedicated `AdminSeeder` (idempotent — safe to re-run)
+- No self-registration on the admin panel — access is granted only via the `is_admin` flag
+
+---
+
+## 2. Dashboard Page
+
+Default landing page. Four `StatsOverviewWidget` cards:
+
+| Stat | Source | Alert |
+|---|---|---|
+| Total users | `users` count | — |
+| Stations in DB | `stations` count + `max(last_seen_at)` | — |
+| Latest oil prediction | Most recent `price_predictions` row — direction, confidence, source | Yellow if > 24h old |
+| API errors (24h) | `api_logs` where `status_code >= 400` or `error IS NOT NULL`, last 24h | Red if > 0 |
+
+No charts on the dashboard — keep it scannable. Charts live inside individual resources.
+
+---
+
+## 3. Resources
+
+### 3.1 Users (`UserResource`)
+
+**Purpose:** View all registered users, manage admin flag, correct postcodes.
+
+**Table columns:** name, email, postcode, is_admin (badge), created_at  
+**Filters:** is_admin toggle  
+**Actions:**
+- Edit: `is_admin` toggle, `postcode` text field (no other fields editable from admin)
+- Delete: allowed (hard delete, with confirmation modal)
+
+**Notes:**
+- No subscription tier column yet — add when Cashier is integrated
+- No impersonation in v1 — add later when user dashboard exists
+
+---
+
+### 3.2 API Logs (`ApiLogResource`)
+
+**Purpose:** Primary debugging tool — see every outbound HTTP call made by the scheduler.
+
+**Table columns:** service (badge), method, url (truncated), status_code (colour-coded), duration_ms, error (truncated), created_at  
+**Filters:** service (select: `fuel_finder`, `fred`, `anthropic`), errors only (toggle: where error IS NOT NULL or status >= 400), date range  
+**Default sort:** created_at DESC  
+**Actions:** View (modal showing full url, full error, request/response if available) — no edit, no delete  
+
+**Colour coding for status_code:**
+- 2xx → success (green)
+- 4xx → warning (yellow)
+- 5xx / null → danger (red)
+
+---
+
+### 3.3 Oil Predictions (`OilPredictionResource`)
+
+**Purpose:** Verify the daily `oil:predict` job is running and producing sensible output.
+
+**Table columns:** predicted_for (date), source (badge: LLM / EWMA), direction (badge: rising/falling/flat with colour), confidence (progress bar 0–100), reasoning (truncated), generated_at  
+**Filters:** source, direction, date range  
+**Default sort:** predicted_for DESC  
+**Actions:**
+- View (modal showing full reasoning text)
+- **Run prediction now** (page-level action): executes `php artisan oil:predict` via `Artisan::call()`, shows success/failure notification
+
+**No edit/delete** — predictions are immutable audit records.
+
+---
+
+### 3.4 Brent Prices (`BrentPriceResource`)
+
+**Purpose:** Verify FRED fetch is populating data correctly.
+
+**Table columns:** date, price_usd  
+**Default sort:** date DESC  
+**Actions:** none  
+
+Simple read-only table. No filters needed — data is always chronological. Include a line chart widget (`BrentPriceChartWidget`) showing the last 30 days using Filament's built-in chart widget.
+
+---
+
+### 3.5 Stations (`StationResource`)
+
+**Purpose:** Browse the ~14,500 UK stations; verify supermarket tagging and closure flags.
+
+**Table columns:** trading_name, brand_name, postcode, city, is_supermarket (badge), is_motorway_service_station (badge), temporary_closure (badge), last_seen_at  
+**Filters:** is_supermarket, is_motorway_service_station, temporary_closure, permanent_closure, postcode prefix (text search)  
+**Search:** trading_name, brand_name, postcode  
+**Default sort:** last_seen_at DESC  
+**Actions:**
+- View (modal with full address, amenities, opening_times, fuel_types JSON)
+- **Trigger full poll** (page-level action): dispatches a queued `PollFuelPricesJob` (wraps `fuel:poll --full`) rather than calling Artisan synchronously — full station refresh on 14,500 records would exceed HTTP timeout. Shows "Poll dispatched to queue" notification immediately; result visible in API Logs once complete.
+
+**No edit** — station data is owned by Fuel Finder API, overwritten on each poll.
+
+---
+
+## 4. Resources Planned But Not Built Yet
+
+These will be added once the underlying tables/services exist:
+
+| Resource | Depends on |
+|---|---|
+| Alerts Log | `alerts` table + `NotificationDispatchService` |
+| Scoring Results | `scoring_results` table + `AlertScoringService` |
+| Subscriptions | Cashier integration + `subscriptions` table |
+
+---
+
+## 5. Navigation Groups
+
+```
+Dashboard (no group)
+├── Users
+Data
+├── Stations
+├── Brent Prices
+├── Oil Predictions
+System
+├── API Logs
+```
+
+---
+
+## 6. Build Order
+
+1. Migration — add `is_admin` to `users`
+2. `AdminSeeder` — seed `uovidiu@sent.com` as admin
+3. `AdminPanelProvider` — mount panel, configure auth
+4. `ApiLogResource` — highest immediate value
+5. `UserResource` — manage admin flag
+6. `OilPredictionResource` + run-prediction action
+7. `BrentPriceResource` + chart widget
+8. `StationResource` + full-poll action
+9. Dashboard widgets (last — depends on all resources being stable)
+
+---
+
+## 7. Out of Scope (v1)
+
+- Role-based permissions beyond `is_admin` — single admin user is sufficient
+- Activity log / audit trail of admin actions
+- Dark mode customisation
+- Custom Filament theme — use default
+- Two-factor auth on admin panel — covered by app-level 2FA (Fortify)
