feat: 5568 - optimized search for price locations

[monsieurtanuki]

What

• The location search for prices could lead to prices linked to locations that are no shops at all (e.g. a road).
• In our location search, we can filter on shops and amenities, which brings much more relevant results, especially for cases with ambiguous terms like "carrefour paris", and that will cover the big majority of our expected locations.
• But in some cases, shops are not tagged as shops, but as buildings.
• The solution is to start with expected results (shop and amenity), and to let the user enlarge the search if needed.

Impacted files

• app_en.arb: added a label for "location broader search"

• dao_osm_location.dart: added columns osmKey and osmValue
• local_database.dart: upgraded the version in order to add columns to location table
• location_list_supplier.dart: added optional parameters for optimized search; added fields osmKey and osmValue
• location_query_model.dart: now we use 2 suppliers - optimized and broader
• location_query_page.dart: now display optimized results first, then broader results after a button click
• osm_location.dart: added fields osmKey and osmValue

Thank you @teolemon @g123k for your reviews!

@raphael0202 @raphodn As discussed less than a month ago, the location search needed to be improved.
Now, our algorithm for location search by terms in Smoothie is:

• filter on shop and amenity, in order to have the most relevant results
• if needed (e.g. obvious shop not found), let the user remove that filter and search again

I don't know if it's the method you're currently implementing for the web app. Feel free to make suggestions!
