fix(spec): chart drillDown mode guidance names object-data-table, not TABLE/PIVOT/METRIC

object-metric (objectui#9002/PR objectui#10681, merged) and object-pivot
(objectui#10685/PR objectui#10710, merged) both refuse drillDown.mode at
their TypeScript door now. Only object-data-table still reads it. The
published refusal text an author sees for drillDown.mode on a chart sent
them to all three blocks, two of which now refuse the same key on arrival.

Reword the guidance to name the one block that actually reads mode, and
move its pin. The neighbouring `report` guidance entry is left alone —
out of scope for this card.
