Add a simple DEV mode button to go to jump between the product page and its Open Prices equivalent

What

• Until we have a more sophisticated integration, we can add a simple DEV mode button to go to Open Prices
• The Open Price URL structure is the following: https://prices.openfoodfacts.org/app/products/3178530410105
• We can also add a shortcut somewhere to promote the Web App available at https://prices.openfoodfacts.org/app/

@teolemon I don't know how fast you intend to move with Prices within Smoothie, but instead of a shortcut to the Prices app we could almost display first a read-only page of prices with the current API - something like [price, date, location].
And then a button to the Prices app.

@teolemon For the record I've just added my first price with my flutter demo app.
I've also noted that the product was about 20% cheaper than in the Monoprix next door.

Having prices within Smoothie would entice more people to input prices, indeed. @monsieurtanuki 👍
Would also be curious to build your prototype app.

Just testing it let me imagine the potential new features, like displaying inside the product items an indicative (average) price e.g. in shops within 2km.

Would also be curious to build your prototype app.

It's in https://github.com/monsieurtanuki/openprices but for the moment it's mainly hard-coded values and not intuitive at all.
Following are the features that could be implemented/refined:

• a "login" page with user and password
• an "OSM location finder" (which may be a pain in the neck)
• an "add price" page with text fields
  • barcode
  • price
  • currency
  • OSM location
  • date
• That would be the Minimal Viable Product

Just coded the "OSM location finder".
The app is still not ready.
