Fix(QML): Resolve text overlap in transaction input display

Split transaction input display into two rows to prevent overlap
between short_id and value fields on Android QML interface.

- First row: input index and short_id (with text eliding)
- Second row: value amount and unit (indented)

Fixes readability issues on small screens and long identifiers.
