Graham McIntire 2bb040154a feat: add dynamic capacity tracking for backhaul devices (#113)
For devices with device_role="backhaul", traffic graphs now show capacity
reference lines that update over time based on which interfaces are active.

Features:
- Calculates total capacity per timestamp from active monitored interfaces
- Uses configured_capacity_bps if set, falls back to if_speed
- Capacity adjusts as interfaces go up/down throughout the time period
- Shows as dashed lines at +capacity (inbound) and -capacity (outbound)
- Matches the existing 0-axis graph style

Implementation:
- Small graph (device detail page): Updated build_traffic_json_datasets/2
  and add_capacity_datasets/3 in device_live/show.ex
- Full-page graph: Updated build_traffic_datasets/2 and
  add_capacity_to_full_graph/4 in graph_live/show.ex

The capacity lines provide visual reference for backhaul link saturation,
showing how close actual throughput is to maximum capacity at each point
in time.
