YubNub Upgraded to Ubuntu 24.04

I just finished migrating YubNub from Ubuntu 12.04 (yes, from 2012!) to Ubuntu 24.04. The site is now running on modern infrastructure with PHP 8.3, MySQL 8.0, and HTTPS.

Server and website configuration isn't my main skillset, so I used Claude Code to guide me through the entire process. It helped with everything from Apache configuration to SSL certificate setup to handling MySQL strict mode issues with legacy data.

The migration went smoothly with zero downtime during the DNS cutover. AI really shines for this kind of work - it's like having a sysadmin sitting next to you.

I wrote up the deployment process and committed it to the repo: https://github.com/JonathanAquino/yubnub/blob/master/DEPLOYMENT.md
