feat: replace jest with vitest

[SRWieZ]

Replacing Jest with Vitest 🎉

Works out of the box with ESM and has fewer dependencies. And, error messages are much more clear.

• Updated tests to use vitest instead of. jest
• Added a new mock implementation for the electron module using vitest and a new test file to verify the mocking of the electron module using vitest. (resources/js/electron-plugin/tests/mocking.test.ts)
• Removed a bunch of jest configuration files and dependencies since vitest supports ESM out of the box.
• Bumped dependencies of vite, electron-vite and some eslint and stylelint plugins

But ⚠️ :

• Removed old Jest mocks and tests for clipboard, dialog, and window endpoints (endpoints/clipboard.test.ts, endpoints/dialog.test.ts, endpoints/window.test.ts).
• Mocking Electron is unreliable in both Jest and Vitest. I managed to get some tests working, but others broke. I believe we need to shift to end-to-end tests using Selenium/Playwright and the kitchen-sink app. The remaining tests still verify the boot process of the API server.

This is the best I can do right now 😅
