Subject: [PATCH] feat: live refresh in the download/upload/task info modals

The info modals held a live reference to their model but only rendered
a snapshot taken when opened, so progress, state, duration and speed
froze until the modal was reopened.

Subscribe each modal to the aggregated throttled TransactionsChanged
event while it is visible (subscribed on ShowModal, unsubscribed on
HideModal and Dispose) and re-render on the UI thread, following the
same pattern the transfer tables use.
