Redesign transaction list and add transaction detail view

Transaction list entries are now two lines with more spacing:
- Line 1: humanized age (hover for ISO datetime) + direction (Sent/Received)
- Line 2: counterparty address + amount with symbol
- Clickable rows navigate to transaction detail view

Transaction detail view (placeholder) shows:
- Status, time, amount, from, to, transaction hash
- Back button returns to address detail

Also added "transaction" to VIEWS list in helpers.
