[TASK] Replace localization methods in `PageLayoutController`

The class `PageLayoutController` has some custom methods to fetch data
of localized pages:

* `getLocalizedPageRecord()`
* `getLocalizedPageTitle()`

The same data can be retrieved using the standardized method
`PageRepository->getPageOverlay()`, which replaces the aforementioned
methods.
