Show exact amounts and address titles in transaction detail

- Display full-precision amount (no 4-decimal truncation) in the
  transaction detail view, with native quantity (wei/base units) below
- Both amount and native quantity are click-copyable
- Show wallet/address title above from/to when the address is ours
- Update README Display Consistency to document the exception
