Fix fetchDaysTraded to use reports API with bearer auth and correct daysTraded counting

- Replace fill/ldeps and fill/list approaches with Tradovate reports API
- Add bearer auth to getreport polling (root cause of prior 404s)
- Use endDate = tomorrow to ensure current-session fills are included
- Count all traded days when minDayPnL is 0, otherwise count days >= minDayPnL
- Add PATCH /api/debug endpoint for proxying raw Tradovate API calls
