Resolve Addresses Batch

Batch resolve for paste-a-handful entry: a few free-text address rows, one per pasted line (blanks already dropped client-side but tolerated here). county_fips bounds every row to the soft-selected county, exactly like the single resolve.

max_length is ADDRESS_ROW_CAP, the same cap the inspect endpoint enforces on how many uploaded rows may ride to the client: an upload that reached the review list is exactly the list this endpoint is asked to resolve, so a lower cap here rejects work the server already handed out.

Per-row outcomes for a pasted batch, one row per input in input order.
