feat: 5195 - location search, as a preliminary step

[monsieurtanuki]

What

• This is the first step of Replicate the 'Add a single price' view from the Open Prices web app #5195: the location search.
• It was a good opportunity to refactor the product search into something more generic: basically, a history of queries and a search to perform from a text.
• Special cases for locations:
  • we display previously selected results first in the search page, as most of the time we hang around the same shops (that would make no sense for products)
  • map display

Screenshots

The entry point is in the "dev mode" page: "Temporary access to location search".

Looks very promising 👌

Thank you very much @teolemon for your review!

As I had to refactor the standard product search, don't hesitate to test it again.
Next step will be entering a product price in Smoothie!
