[Bug]: Cancelling Uniswap connection request in in-app browser leaves session stuck until app restart

Nobody has claimed this yet.

**Describe the bug**

This is a recreation of https://consensyssoftware.atlassian.net/browse/WAPI-844

-----

When cancelling (rejecting) a connection request from Uniswap within the MetaMask Mobile in-app browser, the dapp connection flow becomes stuck. After cancellation, subsequent connection attempts—either to Uniswap or other dapps—fail to trigger the connection modal. The following error is logged:

```
(NOBRIDGE) WARN [MetaMask DEBUG]: {"code": -32002, "message": "Request of type 'wallet_requestPermissions' already pending for origin https://pancakeswap.finance. Please wait."}
```

The only way to recover is to fully close and relaunch the app.

Thread where initially reported by @Joao Tavares : https://consensys.slack.com/archives/C097JHB70J0/p1763024568857779

- MetaMask Mobile (in-app browser)
- Observed on main branch build
- Also appears to occur on prod (though test device was running a TestFlight build)
- Reproducible with Uniswap; other dapps (e.g., PancakeSwap) do not appear to trigger it consistently

**Steps to reproduce**

1. Open MetaMask Mobile and navigate to Uniswap in the in-app browser.
2. Attempt to connect the wallet.
3. Cancel (reject) the connection request.
4. Attempt to reconnect to Uniswap or connect to another dapp.

No source files or tests are named. Start by reproducing the cancellation flow in the in-app browser and search for handling of wallet_requestPermissions and pending connection requests. Done means rejecting a Uniswap request clears the stuck state so a later connection opens its modal without restarting the app, with regression coverage for the flow.
