feat(developers): fix approval webhook flow and add ticket parsing service

Change approve endpoint from int to string ticketId to match SilverDESK
GUIDs. Remove body parameter requirement so the endpoint works as a
webhook target. Add DeveloperTicketParsingService to fetch and parse
applicant details from ticket descriptions. Remove redundant ticket
status update from ProvisioningService since SilverDESK action engine
now handles SetStatus/AddNote/AddReply steps.
