feat: update to vue v3

[sekwah41]

Notice

This is a draft pull request and is currently under heavy development. It has been opened to facilitate discussion as the migration will likely require the addition of new components, such as a Vite-compatible version of @cyclonedx/webpack-plugin. This part can be deferred until the primary migration is functional.

Description

This draft pull request initiates the migration from Vue 2 to Vue 3 and switches the build tool from Vue CLI to Vite.

Addressed Issue

This draft PR addresses issue #446, which calls for the upgrade to Vue 3.

Additional Details

This draft is intended to open a discussion while I am trying to create the changes. As part of the migration process, some components and plugins used in Vue 2 may not be directly compatible with Vue 3 or Vite, such as the current use of @cyclonedx/webpack-plugin. A Vite-compatible version of this plugin will be required, though it has been deferred until the core migration is functional.

Key considerations during this migration:

• Component Rewriting: Some components need to be rewritten to comply with Vue 3's composition API and other new syntax.
• Plugin Compatibility: Certain Vue 2 plugins may not have direct counterparts in Vue 3 or may require alternative solutions.
• Vite Configuration: Moving from Vue CLI to Vite involves reconfiguring the build setup, including handling environment variables, aliases, optimisations and build pipelines.
