feat(mqtt): typed tag editor Sparkplug mode + validation
Task 24 (P2): replaces the P1 Sparkplug Validate() stub (always null) and the "not available yet" editor placeholder with real groupId/edgeNodeId/deviceId/ metricName authoring, mirroring MqttTagDefinitionFactory.FromSparkplugTagConfig in both directions -- required ids + optional deviceId, dataType/qos read strictly but only when present (dataType is optional: the birth certificate declares it). One rule is deliberately stricter than the factory: group/edge- node/device ids reject '/', '+', '#' (topic-segment characters a decoded incoming id can never carry, so an authored one that does can never bind); metricName is exempt since Sparkplug's own canonical names use '/' (e.g. "Node Control/Rebirth"). No FullName key is written -- TagConfig carries no identity under v3, and the plan's snippet asking for one was corrected per the brief. A SparkplugB tag now survives save/reopen because its descriptor keys re-infer Mode on load; there was never a 'mode' key to persist.
