[Bug]: List ledger entries fails when pagination is provided

[guoguojin]

This is due to the query updating to use the ledger_entry_time instead of vega_time. The cursor predicate used for constructing the filtering by cursor does not appear to recognise the ledger_entry_time:

{
  code: 13,
  message: "Internal error",
  details: [
    {
      @type: "type.googleapis.com/vega.ErrorDetail",
      code: 260001,
      message: "failed to query ledger entries",
      inner: "building cursor predicate: no field matching column name ledger_entry_time"
    }
  ]
}
