Creates a new account creation request to onboard a client into the brokerage system.

This endpoint accepts parameters similar to those used by AXOS, enabling seamless migration for clients transitioning from AXOS-based platforms.

⚠️ Important Notes

• The account request is successfully created but remains in a pending state awaiting internal review.
• The request may be subject to validation checks and could be declined if any issues are identified during the review process.
• To verify the account status, call GET /v1/accounts/{requestId}.
• To retrieve the full account details, call GET /v1/account/read and provide the accountId as a query parameter. Use the accountId value returned from the response.
