Resolves a constructible incentive id — the id field on /incentives records — to the record it identifies,
regardless of status (an expired program stays resolvable, so a stored quote can show it as expired).

The id is wb1:{state}:{authority_type}:{authority_ref}:{tech}:{subtype}:{program_type}:{variant}[:{slug}],
so any colon-delimited prefix is also valid and returns the matching set: an exact match wins
(count: 1); otherwise matches holds every record under the prefix and disambiguate_on names the next
segment with its distinct values. count: 0 with moved_to means the id was re-minted (data correction) —
refetch with the new id. matches is capped at 200 (truncated: true).
