[WOOMOB-1410][Woo POS][Surveys] Implement persistent flags

[kidinov]

WOOMOB-1410

Description

Implements persistent flags to support Woo POS survey notifications. This adds infrastructure to track:

• Whether the POS has been opened at least once
• Whether survey notifications have been shown to current users
• Whether survey notifications have been shown to potential users

The implementation includes:

• wasOpenedOnce flag in WooPosPreferencesRepository using DataStore (global, not site-specific)
• Survey notification visibility flags in AppPrefs (persist after logout)
• Integration with WooPosItemsViewModel to automatically set the POS opened flag

Steps to reproduce

Not in use yet

Testing information

• Unit tests verify flag persistence and default values
• Tests confirm the POS opened flag is set on ViewModel initialization
• Survey notification flags are tested for both current and potential users

The tests that have been performed

• Unit tests

• I have considered if this change warrants release notes and have added them to RELEASE-NOTES.txt if necessary. Use the "[Internal]" label for non-user-facing changes.
