Add upload/download ratio and period transfer panels to Transmission dashboard

Browse source 
Adds three new stat panels that calculate metrics over the selected time range:
- Upload/Download Ratio with color thresholds (red < 0.5, yellow < 1, green >= 1)
- Downloaded (Period) showing bytes downloaded in selected range
- Uploaded (Period) showing bytes uploaded in selected range

Uses PromQL increase() on existing counter metrics - no new metrics needed.
