Show Outstanding Balances split per direction per currency

When a user has entries in multiple currencies that go in opposite
directions — e.g. an income entry in EUR (user owes the org) and an
expense entry in CAD (org owes user) — the previous row collapsed
both into a single "Owes you" / "You owe" label driven by the net
sats balance. The fiat amounts were displayed via Math.abs(), hiding
the per-currency signs the backend already returns, so the row was
actively misleading: it showed €200 and CA$300 under one direction
when in reality they point in opposite directions.

Render up to two grouped lines instead — "Owes you €200.00" and
"You owe CA$300.00" — using new owesYouFiat / youOweFiat helpers
that filter the signed fiat_balances dict by sign. Net sats stays
as a small caption with an explicit "(receivable)"/"(payable)"
qualifier, since sats can be netted but distinct fiat currencies
can't without a spot rate. Falls back to the old single-line render
when there are no fiat balances (sats-only entries).
