Brainstorming-approved design to normalize GalaxyMxGateway into the standard
Equipment-driver model: retire the SystemPlatform/Equipment namespace split +
the SystemPlatform mirror + the alias-tag/relay machinery, author Galaxy points
as ordinary equipment tags, port native IAlarmSource alarms onto the
equipment-tag materialization path, and add a driver-agnostic server-side
HistoryRead backend (over the existing Wonderware Historian reader). Three
phases (A de-split + UI, B native alarms, C historian); clean break, no
migration converter; one EF migration to drop NamespaceKind.
