beel-es Account Webhooks API
Outbound webhook subscriptions as a sub-resource of the account itself, addressed by `/v1/accounts/{account_id}/webhooks`. The account in the path is the only source of context — the credential does not decide it, and the `BeeL-Active-Company` header plays no part. It is the canonical form of the operations that `Webhooks` still exposes under `/v1/webhooks`.
