v0.3.0 - Initial 2024 migration

This is the third release of this fork (0.1.1 gathered minor fixes that were submitted as PRs to the upstream but never merged; 0.2.0 introduced the ability to run using Docker). This release covers:

• Migration from Log4j1 to Reload4j due to CVEs unfixable otherwise
• Upgrade from Express 3 to 4 due to CVEs unfixable otherwise
• Migration from Jade 1 to Pug 3 due to CVEs unfixable otherwise
• Upgrade from Node 7 to Node 18 to run on a supported release
• Upgrade from Java 8 to Java 21 to run on a supported release and to make Jena 5 migration possible
• Upgrade from Jena 2 to Jena 5 due to CVEs unfixable otherwise
• A CI matrix for frontend and backend (though lacking in terms of testing)
• Switch from the Dosis font to Inter to improve readability.

A total of 123 security notices by Dependabot were triaged.
