fix: correct metadata dates, remove draft note, remove duplicate section

- Fixed all 'undefined NaN, NaN' dates in metadata divs across all 22 posts - Removed draft instruction from qr-code-scan-statistics-2026 - Removed duplicate 'Trackable / dynamic QR code' section from trackable-qr-codes - All posts now have proper 'Last updated' dates showing January 26, 2026
