Fix date formatting in Partner Ledger report to use locale settings

The _lines() method fetched the language date_format but never applied
it (line was a no-op: r['date'] = r['date']). Now formats dates using
strftime with the user's locale format (e.g. dd.mm.yyyy for bs_BA).
Also added widget='date' to header date_from/date_to fields.
