fix: the balance lists and Home cut amounts to four decimals (closes #757 )

The balance lists and Home's ETH line rounded with toFixed(4), so 0.99996 ETH read 1.0000 there and 0.9999 on Send. They now cut the stored decimal string with truncateAmount(), as the history rows do. balanceLine() takes the stored balance string instead of a parsed number, and escapes the quantity cell. The screens that state what is authorized keep the floor of truncateAmountNeverZero(). Model: opus-5-5
