Reduce history wildcard payloads and add runtime virtual-interface prefix filtering

[jshessen]

Depends On

• Add virtual_interface_prefixes to default configuration pm_auto#2

Related

• Add exclude_prefixes parameter to get_macs/get_ips for virtual interface filtering sf_rpi_status#1

Problem

Wildcard history queries can return legacy transient keys, inflating payload size and latency on Docker hosts.

Change

• DataLogger: add configurable virtual_interface_prefixes and apply exclusions when collecting ip_* and mac_*
• Database: resolve stable field keys and replace broad wildcard key expansion with filtered field selection
• PMDashboard: add POST /api/v1.0/set-virtual-interface-prefixes and propagate updates to logger/database
• PMDashboard: apply configured filtering in network interface listing endpoint

Verification

• python3 -m py_compile pm_dashboard/data_logger.py pm_dashboard/database.py pm_dashboard/pm_dashboard.py
• Workspace diagnostics report no new errors in changed pm_dashboard files

Impact

Reduces history query response size/latency and keeps virtual interface filtering configurable at runtime.
