[Local Catalog] POS Settings: add local catalog sync settings UI

[jaclync]

Part of WOOMOB-1100

Description

This PR adds the UI for POS local catalog sync settings with mock data behind the i1 feature flag. It introduces a new settings detail view that allows merchants to view & configure local catalog sync options for POS. The sync status integration requires more changes which will be included in a future PR.

The implementation includes:

• New POSSettingsLocalCatalogDetailView that provides the interface for catalog settings
• Integration with PointOfSaleSettingsView to display the local catalog settings option behind the local catalog i1 feature flag

Steps to reproduce

1. Log in to a store eligible for POS if needed
2. Tap on the POS tab
3. Navigate to POS Settings (ellipsis menu > Settings)
4. Look for "Local Catalog" option in the settings list
5. Tap on "Local Catalog" --> the catalog settings should be shown with mock data and consistent layout as other settings

Testing information

I tested that when the feature flag is disabled, the catalog settings isn't shown. Tested in iPad A18 iOS 18.4 simulator.

• I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.
