Feat/vitest

[LoTerence]

Fixes #670

Changes

• install vitest and required dependencies
• configured vitest
• migrate old jest tests to vitest
• reinstalled package-lock.json and node_modules
• uninstalled jest and its dependencies

Minor changes:

• added named volume for node_modules to docker compose. The vite container wasn't working on windows before, and naming the volume helped to debug it.
• installed package eslint-config-prettier to fix a linter issue, since eslint got updated to version 9.25.1 in the new package-lock.json
• linted frontend files - mostly effected changes to tailwind classnames order in some components

How it works

In the /frontend folder, run the command:

npm run test

It should say all tests pass, although there are some warnings:

How to test this PR
