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 Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
