DOCKERDISC v2: optional device creation for LAN-visible containers - #1800
Conversation
Maps DOCKERDISC to CurrentScan (scanMac/scanCreatesDevice/scanParentMAC/ scanLastIP) so a container on a macvlan/ipvlan network can opt into creating or confirming its own device, parented to its Docker host. Gated by a new DOCKERDISC_CREATE_DEV setting (default off). A container without its own MAC (bridge/overlay/etc.) never creates a device either way - the framework's blank-scanMac guard blocks the whole group regardless of the setting. Reuses the existing objectPrimaryId/extra column definitions (already host MAC / container IP) to also feed scanParentMAC/scanLastIP, so every promoted container is auto-parented to its host with no extra plugin logic. Two new hidden columns (helpVal1/helpVal2) carry the per-container scanMac/scanCreatesDevice values. Tests: 33 -> 35, both DOCKERDISC_CREATE_DEV on/off paths asserted. Live-verified end to end against a real built image (docker-socket-proxy + isolated macvlan/bridge test containers), since IMPORT_ON isn't in any released NetAlertX image yet.

In `@server/plugins/dockerdisc/config.json`:
- Line 40: Add the DOCKERDISC_IMPORT_ON configuration declaration in the plugin
configuration with its intended default before the CurrentScan mapping is
enabled, so server/plugin.py can correctly gate CurrentScan promotion when
pluginEvents is non-empty. Keep CREATE_DEV exclusively controlling
scanCreatesDevice and do not reuse it for import gating.

Declares DOCKERDISC_IMPORT_ON (default on) so an operator can fully opt this plugin out of CurrentScan promotion. Needed because DOCKERDISC_CREATE_DEV alone doesn't cover it: a macvlan/ipvlan container's row always carries a real scanMac, so even with CREATE_DEV off, an already-existing device for that MAC (found independently by ARP/Nmap) still gets its presence/devLastIP/ devParentMAC updated by this plugin on every run - only IMPORT_ON can turn that off. The two settings are independent, per jokob-sk's PR feedback - IMPORT_ON gates promotion for the whole run, CREATE_DEV gates device creation per row. Also adds missing docstrings to process_host()/main() (CodeRabbit docstring-coverage check), matching the style already used elsewhere in this file.

a couple of small tweaks but looks good to merge after those are fixed

Shorten description - implementation and config details should be in readme - this string is shown in the UI

Shortened to one line in b175a3b - moved the implementation detail to README.

Also map scanSourcePlugin, unlike every other CurrentScan-mapped plugin, - currently every row it inserts gets scanSourcePlugin = NULL.

Added - same Dummy-column static-value pattern arp_scan already uses, in b175a3b.
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.

Adds optional device creation for Docker containers with their own LAN-visible MAC (macvlan/ipvlan), building on
IMPORT_ON. A container'sDOCKERDISCrow can now promote to its ownDevicesentry, parented to its Docker host - gated behind a newDOCKERDISC_CREATE_DEVsetting (off by default).DOCKERDISC_IMPORT_ONandDOCKERDISC_CREATE_DEVare independent gates, not one wrapping the other:IMPORT_ONis a run-level switch - it controls whether any of this run's rows get promoted intoCurrentScanat all.CREATE_DEVis per-row - it only controls whether a container with its own MAC is allowed to originate a new device viascanCreatesDevice.A container without its own MAC (bridge/overlay/etc.) never creates a device either way -
scanMacstays blank for that row, and the framework's blank-MAC guard blocks the whole group regardless ofCREATE_DEV.Column mapping (
