Reconstruct Endpoint

Reconstruct environmental state at a location and date.

Returns the regional baseline table values for the location and NULL (with a reason) for every date-specific observation: no historical archive is queried yet, so this is NOT evidence.

Pricing: Included in subscription tiers (legacy list price: GET /api/v1/billing/pricing).
