feat(mtconnect): serve DATA_SET/TABLE as compact JSON strings; park EVENT enumerations (#650)

Browse Source 
Parser captures Entry/Cell content; the observation index merges /sample deltas
into the /current baseline (resetTriggered replaces, removed deletes, UNAVAILABLE
drops). Fixture gains a TABLE item and periodic DATA_SET/TABLE churn.
