iPad: show the commit card for host-run and pending-approval commits too

Extend the git commit card beyond the Bash transcript path to the other two
surfaces a commit appears on, so all three read like the Mac:

- ApprovalCardView: a pending `git commit` approval (Bash or host_exec) renders
  the structured commit card (subject + Markdown body) with the literal command
  under "Show command", instead of a raw blob or the generic host breakdown --
  so you see exactly the message you're granting.
- HostExecToolCard: a host-run `git commit` surfaces the commit card in its
  expanded body (the `$ command` already sits in the header), rather than only
  the generic "Commit changes" purpose.

Both reuse GitCommitSummary.parse + GitCommitCard from the previous commit.
