fix(sharing): widen the grant db slice for the expired-row sweep

The pre-create sweep in inviteGrant writes an audit row when it closes a
lapsed grant, so the transaction slice it accepts now covers auditLog
alongside accountGrant. Point the module and route test fakes at the
same shape: they stub updateMany to close nothing, so the audit branch
stays unreached in the unit fixtures.
