Framework Upgrade

This also helped improve site-wide performance.

Biggest Update Since Launch
Since Web ToolBox first went live, this is one of the biggest updates yet.
In addition to the tools and improvements we've built up over time, this release revisits the foundation of the site itself.
Here are the main changes.
- Updated from Nuxt 2 (Nuxt Bridge) to Nuxt 3
- Updated from Vuetify 2 to Vuetify 3
- Updated various libraries
- Improved and refined existing tools
- Improved performance
- Refreshed the interface and color design for a more user-friendly experience
Why This Was a Major Update
This update centered on moving to Nuxt 3 and Vuetify 3 and reworking an aging setup.
The goal wasn't just to keep up with new versions, but to reshape the project so new tools and improvements are easier to build going forward.
The migration involved plenty of breaking changes, and updating the related libraries made it a substantial piece of work. Still, by reorganizing the structure and revisiting the codebase from end to end, we were able to improve both usability and performance.
This release doesn't add new tools, but it marks an important milestone as groundwork for what comes next.
We already have more tools we'd like to add, along with requests we've received, so we'll keep expanding the toolbox over time.
