- Add tz.py with local_strftime/to_local helpers that read system.timezone from DB and convert UTC datetimes to venue local time before formatting - Fix all strftime() calls in orders.py, reports.py, printer_service.py that were formatting UTC datetimes without timezone conversion - Fix get_order endpoint returning raw dicts without Z suffix on datetimes, causing JS new Date() to treat timestamps as local instead of UTC - Fix fmtDate() in tokens.js that stripped the T separator before parsing, breaking UTC-to-local conversion for all report date displays - Make open/partially_paid table chips more visually distinct on dashboard Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
