Refracto: update more code to ts

[AugustinMauroy]

Description

Refracto to have more file in ts:
it's allow to have type-check and it's "securise" our code

Note

There are still files written in javascript, either they are used in the next.config.js so they remain in js for the form but if SWC transpiles the ts.
And there are also node scripts, but you'd need to have a loader or be in node 22.
So for the moment I'd rather do nothing for those.

Validation

• All test should pass
• Website should display correctly (use Vercel preview)

Check List

• I have read the Contributing Guidelines and made commit messages that follow the guideline.
• I have run npm run format to ensure the code follows the style guide.
• I have run npm run test to check if all tests are passing.
• I have run npx turbo build to check if the website builds without errors.
• NA I've covered new added functionality with unit tests if necessary.

FYI many of these files are intentionally done in plain JS -- so that they do not need to be transpiled by TypeScript.

There is no virtual benefit (necessarily) for having them in TypeScript. What's the motivation behind this change?

For me, it's ‘important’ to have them in typescript, for example next.dynamic, which is responsible for the entire content of the site. Because typescript offers type-checking which allows us to check that our code is correct and is supposed to help with the review.
We shouldn't all write in typescript in ‘wow that's typescript’ mode but see it more as a tool to limit errors.
