Add server maintenance script (update-server.sh)

[brainless]

Problem

Currently, there is no dedicated script for server maintenance operations like system updates and reboots. Server administrators need to manually SSH and run commands, then manually verify services are back up.

Analysis of Current Scripts

Existing update functionality:

• • (initial setup only)
• • (only when build dependencies missing)
• • (only for certbot installation)

Existing monitoring:

• • Comprehensive service health checking script

Proposed Solution

Create that provides:

1. System Updates

   • Package cleanup if needed

2. Graceful Service Management

   • Stop LetsOrder service before reboot
   • Stop nginx if needed

3. Reboot with Verification

   • Initiate reboot
   • Wait for server to come back online
   • Automatically run health checks using existing logic

4. Post-Reboot Verification

   • Service status checks (letsorder, nginx)
   • Health endpoint verification
   • Resource usage monitoring

Technical Requirements

• Follow existing script patterns (SSH_OPTS, colored output, error handling)
• Use same configuration approach (SERVER_IP, SSH_KEY_PATH from .env or CLI)
• Integrate with existing functionality
• Handle SSH reconnection after reboot
• Proper timeout handling for reboot process

Usage Example

./deployment/scripts/update-server.sh <server-ip> <ssh-key-path>
./deployment/scripts/update-server.sh  # Uses .env configuration
