[Domain Control][Release 3.3] [BE] Add optional domainAccountID param to LockAccount and send related Onyx error updates under `domainErrors_`

[rayane-d]

Part of #76750

---

Problem

LockAccount needs to send Onyx error data in the following format:

domainErrors_<domainAccountID>?.memberErrors?.[<domainMemberAccountID>]?.lockAccountDetailsErrors

Currently, we don't have logic to send errors under the domainErrors_ Onyx key for the LockAccount endpoints. It only returns errors to account.lockAccount.errors

---

Solution

• Accept an optional domainAccountID parameter, since these endpoints are also used elsewhere
• Add BE logic to send errors under the domainErrors_ Onyx key
