Adds the AutoFill Credential Provider Extension target (App Group + Keychain Sharing capabilities, autofill-credential-provider entitlement), removes the leftover SwiftData bootstrap from MyPassApp.swift now that Item.swift is gone, and switches the bundle ID / App Group / Keychain group prefix from com.christophevila to org.antiloop222 to match the project's existing identifier.
