[Bug]: Confirmations Navigation- Reject All appears in the navigation header when I have a STX Confirmed page with another tx/signature

Nobody has claimed this yet.

**Describe the bug**

Whenever I have queued 2 tx's (or 1 tx and a singature) if that is a smart transaction, whenever I confirm the STX I can see how the STX confirmation screen is displayed afterwards and I am able to `Reject all` the 2 confirmations, despite the STX one being just informative (no reject possible).

Note: I suspect that's already in prod, but cannot check as STX don't work for me there with Sepolia

**Steps to reproduce**

1. Enable STX
2. Trigger a signature or tx
3. Trigger a tx
4. Confirm the tx
5. See how the navigation displays 2 screens, and Reject all, despite the tx screen being now the STX confirmation/informative page

**Error messages or log output**

```shell

```

**Detection stage**

During release testing

**Version**

12.13.0

**Build type**

None

**Browser**

Chrome

**Operating system**

Linux

Reproduce the flow in Chrome on Linux by enabling STX, triggering a signature or transaction followed by another transaction, and confirming it. Inspect the confirmation navigation state after the STX confirmation page appears; done means the informative STX page does not leave an actionable “Reject all” option for the remaining confirmations.
