Applies ESLint code formatting

[IDisposable]

Summary

Upgraded all the ESLint and enforced the current rule set to get consistent code style across the UI codebase. It primarily consists of changes automatically applied by ESLint and Prettier.

• Enforces consistent code style: Applies a comprehensive lint fix pass to adhere to updated ESLint rules and the current Vite project build structure.
• Improves readability: Reorders Tailwind CSS classes for consistency and makes minor adjustments to whitespace and code structure.
• No functional changes: These modifications are purely stylistic and do not alter the behavior or functionality of the application.

Details

• Created a new Vite project with all the required packages and synched up the structure
• Move the eslint.config.cjs to eslint.config.js as this was the only .cjs file in the whole system
• Follow the current vite practice of split tsconfig.json into tsconfig.app.json and tsconfig.node.json
• Added lint:only and lint:fixonly when no localization needs compiling
• Eliminated unused lodash.throttle package
• Moved the eslint-import-resolver-alias to the devDependences
• Add missing typescript-eslint to devDependencies
• Don't force blank lines between import groups (but allow them)
• Allow slightly longer lines
• Upgraded to Node 22.21.1 (current for LTS 22)
• Upgraded packages

This changes everything ;) It was just a run of npm run lint:fix after all the package cleanup (pulling in vite 7.2.2 made a lot of things complain in eslint).

This one-time pass will enable us to put the eslint check that PR #491 was attempting to enable :)
