feat(helpdesk): add ticket file download and inline image preview

Browse Source 
New SOAP method getTicketFile() on BcSoapGateway calls BC's
GetTicketFile to retrieve file attachments as Base64, decodes in
memory and returns binary data without writing to disk.

New proxy endpoint helpdesk/ticket-file-data streams files directly
to the browser with correct MIME type. Images served inline, other
files as download attachment.

TicketCommunicationService now attaches file_entry_no and file_name
to file-type events. Frontend renders download links with bi-download
icon and inline image previews for jpg/png/gif attachments.

Works in both ticket detail and debitor detail communication feeds.
