Recover stashed driver-gaps work from pre-v2-mxgw-merge working tree

Captures uncommitted work that lived in the working tree on
v2-mxgw-integration but was orthogonal to the migration. Stashed
during the v2-mxgw merge to master (2026-04-30) and replanted here on
a feature branch off master so it's git-visible rather than living in
the stash list.

Two distinct buckets:

1. Tracked fixture/config refinements (10 files, ~36 lines):
   - scripts/e2e/test-opcuaclient.ps1
   - src/ZB.MOM.WW.OtOpcUa.Admin/appsettings.json
   - 5 docker-compose.yml under tests/.../IntegrationTests/Docker/
     (AbCip, Modbus, OpcUaClient, S7)
   - 4 fixture .cs files (AbServerFixture, ModbusSimulatorFixture,
     OpcPlcFixture, Snap7ServerFixture)

2. Untracked driver-gaps queue artifacts (~8000 lines):
   - docs/plans/{abcip,ablegacy,focas,opcuaclient,s7,twincat}-plan.md
     — per-driver gap plans
   - docs/featuregaps.md — cross-cutting analysis
   - docs/v2/focas-deployment.md, docs/v2/implementation/focas-simulator-plan.md
   - followup.md — auto/driver-gaps queue follow-ups
   - scripts/queue/ — PR-queue automation tooling (12 files including
     pr-manifest.yaml at 1473 lines)

This commit is a snapshot for recoverability — review and split into
focused PRs (or discard) before merging anywhere downstream.
