feat(api): include voided transactions in user-entries endpoint

The /api/v1/entries/user view was silently dropping any transaction tagged
'voided', so users couldn't see entries that had been rejected against
their accounts. Per the libra reject convention, voided entries keep the
'!' flag and carry a 'voided' tag for audit; clients can use the tag to
style them distinctly. Pending-approval listing still filters voided.
