Add Network monitoring for LAN/WAN clients into the Server Resources dashboard

[ramphex]

• Adds streaming bandwidth/network metrics to the Server Resources dashboard
• Displays LAN and WAN client bandwidth alongside existing CPU and memory metrics, refreshes at the same interval
• Aggregates active session bitrates to compute total bandwidth (paused sessions do not count)
• Bandwidth reflects streaming usage, not host NIC-level throughput

Screenshot with one remote stream + one local stream running, then paused, then started back up
