feat(libra): color-code income/expense entries and add type filter

Transaction History now shows a left green/red stripe on each card and
tints the matching income-entry/expense-entry tag badge — mirrors the
Record page's red/green palette so the two screens read consistently.
Adds an All / Income / Expenses filter row (with Filter icon, aligned
to the Calendar-iconed date range row above) that applies on top of
search and date filtering.
