Change ticket IDs from UUID to sequential integers

Backend:
- tickets.id: uuid → integer GENERATED ALWAYS AS IDENTITY
- transactions.ticket_id, custom_field_values.ticket_id: uuid → integer
- Routes convert string params to Number() for DB queries
- ScripEngine.prepare takes ticketId: number
- ActionPayload.ticketId: string → number

Frontend:
- Ticket.id: string → number, Transaction.ticket_id: string → number
- API functions accept number params
- formatTicketId() helper returns TKT-0001 format
- Ticket rows display TKT-XXXX, detail page uses formatTicketId

Migration: drops FKs, clears data, alters column types, re-adds FKs
