Settings-UI description trimmed to one short line - implementation
detail (Socket Proxy, column mapping, CREATE_DEV behavior) already
lives in README, doesn't belong in the Settings page string.
scanSourcePlugin now maps to a static "DOCKERDISC" value (same
Dummy-column pattern arp_scan already uses), so a container device
created by this plugin gets devSourcePlugin set correctly instead of
NULL - every other CurrentScan-mapped plugin already does this.
