Rename test metrics with clear prefix and add Grafana dashboard

Renamed all test metrics with "prometheus_pusher_test_" prefix to clearly
indicate they are generated by the prometheus-pusher testing/demo functionality.

Metric renaming:
- app_requests_total → prometheus_pusher_test_requests_total
- app_active_connections → prometheus_pusher_test_active_connections
- app_temperature_celsius → prometheus_pusher_test_temperature_celsius
- app_request_duration_seconds → prometheus_pusher_test_request_duration_seconds
- app_jobs_processed_total → prometheus_pusher_test_jobs_processed_total

Grafana Dashboard:
- Created comprehensive dashboard with 8 panels
- Request rate and total requests visualization
- Active connections gauge (0-100 with thresholds)
- Temperature gauge (0-50°C with thresholds)
- Request duration percentiles (p50, p90, p99)
- Average request duration stat
- Jobs processed by type (bar gauge)
- Jobs status breakdown table
- Auto-refresh every 10s, 15-minute default time range

Files added:
- grafana-dashboard.json: Dashboard definition
- deploy-dashboard.sh: Automated deployment script
- DASHBOARD.md: Complete dashboard documentation

Updated:
- internal/metrics/generator.go: Renamed metric names
- internal/ingester/remotewrite.go: Updated historic metric names
- internal/ingester/remotewrite_test.go: Updated test expectations

Tests updated and passing with 63.9% coverage maintained.

+# Grafana Dashboard for Prometheus Pusher Test Metrics
+
+This document describes the Grafana dashboard for visualizing metrics generated by prometheus-pusher.
+
+## Dashboard Overview
+
+The dashboard displays all test metrics with the `prometheus_pusher_test_` prefix, making it clear they are generated by the prometheus-pusher testing/demo functionality.
+
+## Metrics Displayed
+
+### 1. Request Rate
+- **Type**: Line graph
+- **Metric**: `rate(prometheus_pusher_test_requests_total[5m])`
+- **Description**: Shows the rate of requests per second over the last 5 minutes
+- **Use**: Monitor request throughput
+
+### 2. Total Requests
+- **Type**: Stat panel
+- **Metric**: `prometheus_pusher_test_requests_total`
+- **Description**: Counter showing total number of requests processed
+- **Display**: Large number with area graph background
+
+### 3. Active Connections
+- **Type**: Gauge
+- **Metric**: `prometheus_pusher_test_active_connections`
+- **Description**: Current number of active connections (0-100)
+- **Thresholds**:
+  - Green: 0-50
+  - Yellow: 50-80
+  - Red: 80-100
+
+### 4. Temperature
+- **Type**: Gauge
+- **Metric**: `prometheus_pusher_test_temperature_celsius`
+- **Description**: Current temperature in Celsius (0-50°C)
+- **Thresholds**:
+  - Blue: 0-20°C
+  - Green: 20-30°C
+  - Yellow: 30-35°C
+  - Red: 35-50°C
+
+### 5. Request Duration Histogram
+- **Type**: Line graph
+- **Metrics**:
+  - `histogram_quantile(0.50, rate(prometheus_pusher_test_request_duration_seconds_bucket[5m]))` - p50
+  - `histogram_quantile(0.90, rate(prometheus_pusher_test_request_duration_seconds_bucket[5m]))` - p90
+  - `histogram_quantile(0.99, rate(prometheus_pusher_test_request_duration_seconds_bucket[5m]))` - p99
+- **Description**: Shows request duration percentiles over time
+- **Use**: Identify latency trends and outliers
+
+### 6. Average Request Duration
+- **Type**: Stat panel
+- **Metric**: `rate(prometheus_pusher_test_request_duration_seconds_sum[5m]) / rate(prometheus_pusher_test_request_duration_seconds_count[5m])`
+- **Description**: Average request duration in seconds
+- **Display**: Number with area graph, 3 decimal places
+
+### 7. Jobs Processed by Type
+- **Type**: Bar gauge
+- **Metric**: `sum by (job_type) (prometheus_pusher_test_jobs_processed_total)`
+- **Description**: Total jobs processed grouped by job type (email, report, backup)
+- **Display**: Horizontal gradient bars
+
+### 8. Jobs Status Breakdown
+- **Type**: Table
+- **Metric**: `prometheus_pusher_test_jobs_processed_total`
+- **Description**: Detailed breakdown showing job type, status, and count
+- **Columns**: Job Type, Status, Count
+
+## Deployment
+
+### Prerequisites
+- Grafana instance running and accessible
+- Prometheus as a data source in Grafana
+- Metrics being pushed to Prometheus via prometheus-pusher
+
+### Deploy via Script
+```bash
+# Port-forward to Grafana (if running in Kubernetes)
+kubectl port-forward -n monitoring svc/prometheus-grafana 3000:80
+
+# Deploy dashboard (in another terminal)
+./deploy-dashboard.sh
+```
+
+### Deploy Manually
+1. Open Grafana UI
+2. Go to Dashboards → Import
+3. Upload `grafana-dashboard.json`
+4. Select Prometheus data source
+5. Click Import
+
+### Custom Deployment
+```bash
+# With custom Grafana URL and credentials
+GRAFANA_URL="http://grafana.example.com" \
+GRAFANA_USER="admin" \
+GRAFANA_PASSWORD="secret" \
+./deploy-dashboard.sh
+```
+
+## Dashboard Features
+
+- **Auto-refresh**: Updates every 10 seconds
+- **Time range**: Last 15 minutes by default
+- **Refresh intervals**: 5s, 10s, 30s, 1m, 5m
+- **Shared tooltips**: Hover over graphs to see all series values
+- **Dark theme**: Optimized for dark mode viewing
+
+## Metric Naming Convention
+
+All metrics use the `prometheus_pusher_test_` prefix to:
+- Clearly identify them as test/demo metrics
+- Distinguish from production application metrics
+- Make cleanup and filtering easier
+- Prevent confusion with real application data
+
+## Testing the Dashboard
+
+1. **Push test metrics**:
+   ```bash
+   ./prometheus-pusher -mode realtime -pushgateway http://localhost:9091
+   ```
+
+2. **Continuous updates** (for live dashboard testing):
+   ```bash
+   ./prometheus-pusher -mode realtime -pushgateway http://localhost:9091 -continuous
+   ```
+
+3. **View in Grafana**:
+   - Navigate to the "Prometheus Pusher Test Metrics" dashboard
+   - Watch metrics update in real-time
+   - Interact with time ranges and refresh intervals
+
+## Cleanup
+
+To remove old test metrics from Pushgateway:
+```bash
+# Delete all metrics for the example_metrics_pusher job
+curl -X DELETE http://localhost:9091/metrics/job/example_metrics_pusher
+```
+
+## Customization
+
+The dashboard JSON file can be customized:
+- Adjust panel sizes via `gridPos`
+- Change colors and thresholds
+- Add new panels for additional metrics
+- Modify queries and aggregations
+- Update refresh intervals
+
+After making changes, redeploy using the deployment script.
