Increase upcoming events window from 72 hours to 5 days

Extended the shopfloor dashboard upcoming events window to show more
advance notice of scheduled changes and incidents.

Changes:
- api_shopfloor.asp: Changed INTERVAL 72 HOUR to INTERVAL 5 DAY
- Dashboard display: "Next 72 Hours" → "Next 5 Days"
- No events message: Updated to reflect 5-day window

Benefits:
- Better visibility for weekly planned maintenance
- More advance notice for upcoming changes
- Aligns with typical weekly planning cycles
