feat: add topBar settings type

[guidobernal-cubos]

What problem is this solving?

This change allows customization of the top bar appearance (name and color) in B2B settings.

How to test it?

Get:

{
  getB2BSettings {
    uiSettings {
      showModal
      clearCart
      topBar {
        name
        hexColor
      }
    }
  }
}

Insert:

mutation {
  saveB2BSettings(
    input: {
      uiSettings: {
        showModal: true
        clearCart: false
        topBar: {
          name: "Top Bar Example"
          hexColor: "#FF5733"
        }
      }
    }
  ) {
    status
  }
}
