fix: 4663 - use the latest password for background tasks + refactoring (

#4869)

* fix: 4663 - use the latest password for background tasks + refactoring

Impacted files:
* `background_task.dart`: use the latest password; now we compute user and country from that class, and language most of the time too
* `background_task_barcode.dart`: removed user and country parameters; replaced language
* `background_task_crop.dart`: removed user and country parameters; replaced language
* `background_task_details.dart`: removed user, language and country parameters
* `background_task_download_products.dart`: removed user, language and country parameters
* `background_task_full_refresh.dart`: removed user, language and country parameters
* `background_task_hunger_games.dart`: removed user, language and country parameters
* `background_task_image.dart`: removed user and country parameters; replaced language
* `background_task_offline.dart`: removed user, language and country parameters
* `background_task_paged.dart`: removed user, language and country parameters
* `background_task_progressing.dart`: removed user, language and country parameters
* `background_task_refresh_later.dart`: removed user, language and country parameters
* `background_task_top_barcodes.dart`: removed user, language and country parameters
* `background_task_unselect.dart`: removed user, language and country parameters
* `background_task_upload.dart`: removed user and country parameters; replaced language
* `paged_to_be_completed_product_query.dart`: minor refactoring
* `paged_user_product_query.dart`: minor refactoring

* fix: 4663 - lint fix
