Function ticket_factory_from_chain 

pub async fn ticket_factory_from_chain<C>(
    connector: &C,
) -> Result<Arc<HoprTicketFactory<RedbStore>>, TicketManagerError>
where
    C: ChainReadChannelOperations,
    C::Error: Display,

Creates a HoprTicketFactory backed by a temporary RedbStore and pre-seeds it from the node’s current outgoing channels.

Use this when building an edge (entry/exit) node that issues tickets but does not relay them. For relay nodes that also manage incoming tickets, use ticket_manager_from_chain instead.
