fix(web): stop large balances clipping on the statement page

TRASPASOS PAYPAL's 7-figure balances exposed three layout bugs on
/estado-cuenta/[id], all invisible on normal small-figure customers:

- summary/línea cards: `summary-grid` uses auto-fill, so a single- or
  two-currency card never widens past the min track (~190px) however wide
  the page is. The 24px nowrap headline (-$7,028,533.44) overflowed the
  card border. Widen the min track to 260px so the figure fits in full,
  and drop the size to 22px. Explicitly no ellipsis — a truncated money
  figure reads as a wrong number.
- `concept-list` had no horizontal padding (`.card` carries none), so the
  concept totals sat flush on the card border. Pad it.
- the Cargo/Abono direction label was an inline span glued to the amount;
  make it a block so it drops onto its own line. Same fix applied to the
  movement-list page for consistency.
