fix: history rows show the ISO datetime and the age (closes #760)

Home, AddressDetail and AddressToken showed only the relative age, with
the datetime as a tooltip. Each row now shows the datetime and then the
age in parentheses, on a line of its own, through transactionTimeHtml()
in helpers.js, which TransactionDetail also uses. The direction label
moves to its own right-aligned line below.
