Review and Update vue.config.js

[rak-phillip]

Recent updates to Dashboard include significant changes that may have impacted vue.config.js:

• Migration from Nuxt to Vue.js
• Upgrade from Vue 2 to Vue 3
• Upgrade from Webpack 4 to Webpack 5

With these changes in place, it's a good time to review shell/vue.config.js to ensure that the configuration is still relevant, not overly complicated, and functioning as expected.

Proposed solution

• Verify that all configurations in vue.config.js are still necessary
• Review and address the TODO items in shell/vue.config.js
• Add explanations for any logic in vue.config.js that may not be immediately clear

Acceptance criteria

• vue.config.js is updated and optimized
• All TODO items are addressed and resolved
• vue.config.js includes clear explanations for any non-obvious logic

Additional info

After encountering #12244, I thought it would be best to confirm that there aren't any other unexpected surprises with regards to how Dashboard is built and bundled.
