Retrieve the initial cap table.
Initial cap-table snapshot reconstructed from the first share-ledger entry per share class. Used by 83(b) generation, articles-of-amendment diffs, and the formation packet's founder-allocation block. Distinct from GET /v1/entities/{id}/cap_table (current state) — this endpoint returns the cap table as it was at incorporation.
Errors: 400, 401, 404, 429.
