feat: 5855 - no visible product type filter by default

[monsieurtanuki]

What

• Now the servers provide product field "product_type", and we do retrieve that value.
• We overwrite this product field with the value inherent to the server, but only if it is null on the product side, for some reason or for "old" products.
• There's a switch in order to hide the "product type" text search filter (hidden by default).
• No change for the barcode search: we try to find that barcode on all 4 servers.

Screenshots

switch off (default)	switch on

Fixes bug(s)

• Closes: #5855

Impacted files

• background_task_price.dart: minor unrelated fix due to off-dart 3.17.0
• dao_product.dart: we overwrite the products product_type with the server product type only if null
• product_query.dart: now retrieving product_type field in products found on a server
• product_refresher.dart: unrelated minor refactoring
• pubspec.lock: wtf
• pubspec.yaml: upgraded off-dart to 3.17.0
• search_product_helper.dart: visible/invisible product type filter, by default invisible and working on food
• user_preferences_dev_mode.dart: on/off switch for visible product type filter, off by default

Generally speaking, seems OK.

However, we don't want the settings in the DEV mode, but directly in the App Settings, in the Products section (sorry, I wasn't specific enough). Also, I would maybe change the setting to enable it (not the other way around)

Understood, but I'm currently visiting family in Italy and I won't be able to change anything before Friday.

Good. I guess we're all set then.
