Add a filter for jobs with staff accommodation

It would be very useful to have a specific filter for jobs that include staff accommodation or subsidized housing, especially for seasonal workers moving from another country.

Right now, many job seekers have to open every listing manually and search for words like "accommodation", "housing", "Unterkunft", "Personalzimmer" or "staff room". A dedicated filter would save a lot of time and make the search much more relevant.

This would be especially helpful for hospitality, hotel, restaurant and seasonal jobs in Switzerland and other high-cost countries.
