feat(adminui): Transport dropdown on AbCip/AbLegacy driver forms (live-verified on docker-dev)

- AbCip/AbLegacy driver forms gain a Transport InputSelect; FromOptions/ToOptions now carry
  Transport, so saving any other field no longer silently reverts Native to libplctag.
- Both drivers log the constructed transport once per init.
- AbCip factory now takes the host ILoggerFactory (it ran on NullLogger in production, hiding
  every AbCip log line); DriverFactoryBootstrap passes it.
- Gate results: AdminUI /run (T19) native, inverted (dead port) and libplctag legs.
