Update SQL script with view changes for uptime tracking

- Replaced add_lastboottime_column.sql with comprehensive add_uptime_tracking.sql
- Updates 3 views to include lastboottime and uptime_days columns:
  - vw_active_pcs: Active PCs with warranty info
  - vw_shopfloor_pcs: Shopfloor PCs
  - vw_recent_updates: Recently updated machines
- Includes verification queries
