refactor: rewrite PersistenceManager with centralized data management

[thkruz]

• Add new EventBusEvent types: buildDataUpdate, buildPreferencesUpdate, debouncedSync
• Implement centralized preferences and userData objects
• Add EventBus listeners for automatic data/preferences updates
• Implement debounced sync with 3-second delay
• Add isUseLocalStorage and isUseRemoteStorage flags
• Sync loop runs when either storage flag is enabled
• Save to localStorage only when isUseLocalStorage is true
• Emit debouncedSync event for external sync (e.g., Supabase)
• All data is properly serialized to JSON
• Load from localStorage on initialization

Breaking Changes:

• Removed old getItem(), saveItem(), checkIfEnabled() methods
• Code using old API will need to be updated to use new preferences/userData objects
