feat(balance): pending chip in the Donut, Shield and Timeline layouts too

Extends the labeled "Pending +X" chip (with its awaiting-confirmations tooltip)
to three more layouts via a shared DrawPendingChip() helper. It draws on the
ticker line (the USD value sits on the line below in these layouts, so there's no
overlap) and is skipped if it would overflow the card. The remaining draw-list
layouts with right-aligned content (Consolidated, Minimal, the grid variants)
are left for a follow-up.
