Fix lint problems

[megatroom]

Description

Current:

$ npm run lint
- 92636 problems (90734 errors, 1902 warnings)

Now:

$ npm run lint
+ 79 problems (64 errors, 15 warnings)

I didn't do any refactoring, I just adjusted the lint settings and fixed the formatting errors.

The remaining errors are logic errors, so I think it's best to stay as a technical debit for an upcoming refactoring.

How to test?

Run the lint and check the fixes.

Expected behavior

Since I haven't changed any behavior, it should continue to work the same way.

Is broken on react components, the cause appears to be file extensions (which is not jsx):
frontend/pages/login/title/title.js 4:3 error Parsing error: Unexpected token <

My suggestion is use only js

"rules": {
  "react/jsx-filename-extension": [1, { "extensions": [".js" }],
}

What do you think?

I think this is great! 🌟

I included this and other rules to support React. I also took the opportunity to add the new React Hooks rules for protection.

You will need run npm install again to test.
