Support attaching a file / pasting a screenshot when creating a new ticket

The "New ticket" modal only took a plain-text message. It now matches the
existing reply box on an open ticket: a "Прикрепить файл" button, and Ctrl+V
paste of a clipboard screenshot attaches it directly. POST /api/tickets
switched from JSON to multipart/form-data to carry the optional file,
reusing the same saveAttachment/attachment-delivery path replies already use.
