Thin typed model over a preserved JsonObject key bag, mirroring the sibling
<Driver>TagConfigModel template. Key names and strictness rules mirror
MqttTagDefinitionFactory rather than inventing an editor-side schema; enums
round-trip as NAMES (the factory reads them strictly by name).
No FullName key: under v3 a tag is identified by its RawPath, which the factory
keys the definition's Name off — a composed identity key here would be dead
weight nothing reads.
Mode is a UI-only sub-shape selector inferred from the blob (any Sparkplug
descriptor key present) and never serialised — the driver takes Plain vs
SparkplugB from its DRIVER config. Only Plain Validate() is implemented; the
Sparkplug branch is a stub Task 24 fills, and its keys are preserved untouched.
