Import cap table.
Bulk-import an existing cap table into Matter. Use when migrating an entity from an external cap-table system or seeding a new Matter entity with historical state. Accepts share classes, share-ledger entries, grants, and stakeholders in a single payload, validates that totals balance, and commits atomically.
Distinct from POST /entities/{id}/cap_table/restate — import is an initial population, restate is a corrective replay against an existing ledger. Both emit cap_table.imported / cap_table.restated events with the diff and an audit reason.
?dry_run=true validates without committing.
