Three confirmed issues from user feedback:
1. Reverse charge preview now uses per-item VAT rates and correct accounts
(2645/2647, 2614/2624/2634) instead of hardcoded 25%/2614
2. Bank sync uses 90-day lookback on first sync (when last_synced_at is null)
instead of hardcoded 7 days for all syncs
3. Bank file import improvements:
- Shared date normalizer supporting DD.MM.YYYY, DD/MM/YYYY, YYYYMMDD
- Silent row skips now reported with reason in issues[]
- Decimal separator mismatch detection in generic CSV
- Swedish error message with format diagnostics on detection failure
- Date format selector in column mapping UI
