feat: new parameters for uploadProof

[monsieurtanuki]

What

• Using the latest Prices and off-dart code, we're now able to set location, date and currency for a proof (and not just for each individual price)

Screenshot

From the Prices app, about a proof created from Smoothie with the current PR code:

As opposed to a proof without location, date and currency

Impacted files

• background_task_add_prices.dart: 4 new parameters for uploadProof
• pubspec.lock: wtf
• pubspec.yaml: upgraded to off-dart 3.12.0
