Improve monitor script to eliminate screen flicker

Instead of clearing the entire screen every 5 seconds, the script now:
- Prints the header once and saves cursor position
- Fetches all API data before updating display (no blank period)
- Restores cursor position and updates only the content area
- Hides cursor during display for cleaner look
- Shows cursor on exit via cleanup trap

Uses tput commands:
- sc/rc: Save/restore cursor position
- ed: Clear from cursor to end of screen
- civis/cnorm: Hide/show cursor
