feat: add creatives table and sectors page

[sebas-memorable]

As requested in the FE test, I added the creatives table in Library page and added a new sectors page.

I created the corresponding .domain, .repository, .page and . widget files and added them trying to follow current project structure. I tried to reuse as much components as I could, in order to not duplicated things.

I had to update schemas.graphql and schemas.ts since the listFolder BE service was replaced by folder. So I had to adjust the query name and add the new types.

I added a date formatter tool to format dates. This tool uses the locale to format the date. By default it uses en-US locale but by passing user's locale as the second parameter, you can get the date formatted in user's locale. I also added some unit test for this.

I had to remove omick dependency from package.json since it wasn't available in yarn repository. Nonetheless, that dependency was not being used.

This is the first time I see this kind of project structure for a React project. It took me a while to understand where each component lives. Even though I see the value provided by this folder structure, I think for a React project there's a more simple approach.

Another thing I found interesting is the use of genql together with swr to communicate with the GQL server. Having to create several files in order to call a GQL query (for instance). I think the same thing could be addressed with apollo client with lot less code.
