- get_domain_mailboxes: was POST /api/v1/get/mailboxes/{domain},
correct path is GET /api/v1/get/mailbox/all/{domain}
- Quota percentage field is percent_in_use, not quota_used_in_percent

Mailcow's GET /api/v1/get/domain/all returns domain_name (not domain)
in each response object. Using the wrong key caused the dropdown to
display 'null' for every entry.
