feat(telemetry): add mongo_query_completed event

Adds the strict mongo_query_completed schema (driver, isDemoConnection,
stageCount, durationMs, outcome, errorClass) for the upcoming
ktx mongo-query command, registered in both the catalog object and the
name/description/fields catalog list, and mirrors it to the Python
daemon schema copy.
