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 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
