Renamed package structure to `nl.astraeus.tmpl` for consistency and modified the repository name placeholder. Updated Kotlin and library dependencies, removed unused imports, and adjusted Gradle settings for better project clarity.
Refactor project to use a constant variable for the repository name. This ensures consistency and reduces the risk of errors when referencing the project name in multiple places. Updates were made in settings.gradle.kts, .gitea/template, and Main.kt to use the REPO_NAME variable.
Updated rootProject.name and JDBC URL configuration to use template placeholders for better flexibility and consistency. Removed unused code and initialization block from Database.kt to improve readability and maintainability.
Upgraded the Kotlin version from 2.0.0-RC1 to 2.0.21 and adjusted various dependencies to their latest versions. Added new Maven repository URLs and updated `.idea` project artifacts to reflect the new versioning and project setup.
