feat(MORG-46): show only valid Jira transitions when changing ticket status (#34)

getStatuses() now accepts an optional ticketId. When provided, it fetches
ticket-specific transitions via /issue/{key}/transitions instead of the
global status list, so the "Change status" menu only shows transitions
valid for the ticket's current workflow state.
