[SF Migration] Harmonize already migrated controllers with latest migration practices

[matks]

As we migrate the PrestaShop backoffice ; we improve our code, the tools we use, the concepts and pattern we apply, the rules we follow. So the 1st controllers that were merged might not comply with the latest improvements we have adopted.

This is why we must have a look at these controllers and check that:

• the CRUD pages comply with Form Entity Management rules
• the CQRS pages comply with CQRS rules [ref missing]
• the Grid pages use the latest features of the Grid component [ref missing]
• they use Domain exceptions
• they comply with templates, routes and controller actions naming conventions
• they provide satisfying performance metrics (see below)
• they are covered, when eligible, by unit tests and e2e tests
• they take care of routing compatibility using legacy links
• ... (this list will be improved)

About performance metrics

We should compare legacy pages with SF pages using BlackFire to check that we did not introduce big latencies.
