feat(goals): footer 'N pending' on cards + drop warning tone from top callout

- Pending pledges surface in the card footer as '· N pending' tacked
  on after the existing footer line (text-subdued). Quiet, semantic,
  doesn't compete with the status pill or the avatar.
- The top-of-page 'You have pending pledges' callout was using the
  amber DS::Alert warning variant. Pending isn't a warning — it's a
  passive 'we're waiting on a sync' state. Switch to the info
  variant so the visual weight matches the meaning.
