feat(api): filter layouts endpoint

[p-fernandez]

What change does this PR introduce?

Adds endpoint to filter layouts by environment.

Why was this change needed?

UI needs a layout manager to list all the layouts an organization has in certain environment. For that this endpoint will be needed to show and paginate all the layouts.

NV-1415 Feature: Get layouts per environment endpoint

Looks good. I'm just not sure filter is the best name for this, as it implies actual filtering for params.
What do you think?
Maybe GetLayouts(that's the format we use in other places) or GetLayoutsList

Probably we will need to add functionality to filter based in layouts being deleted or and by isDefault value. (For this last case we might want a dedicated endpoint though). Also currently we are filtering by environment and organization, though the values are passed in the Auth header, so for me we are actually filtering. That's why I always choose filter. GetLayout and GetLayouts is so easy to make a confusing mistake that if you are adamant on changing it I'd go for GetLayoutList.

No, it's fine. We can keep it as filter❤️
