fix: wait for approval confirmation before swap on mobile HW

[khanti42]

Explanation

QA on MetaMask Mobile saw approve + swap (two on-chain txs) fail on Monad when using a hardware wallet: the swap step could run before the approval was confirmed, so gas estimation / simulation failed (allowance not set yet).

Problem

On Mobile + HW, approve → swap could run the swap before the approval was confirmed, so gas estimation failed (e.g. Monad).

Fix

If Mobile + HW and an approval tx exists, wait for that tx to confirm before submitting the swap; otherwise unchanged.

Mobile PR (see PR#27615)

Yarn patch on @metamask/bridge-status-controller@68.1.0 so QA can verify and cherry pick happen before a core release bumps the dependency.

Note

Medium Risk
Changes EVM non-batch submission sequencing by blocking on approval confirmation for mobile hardware wallets, which could affect transaction timing and error handling in the submission path. Scope is limited and covered by updated unit tests/snapshots.

Overview
Ensures mobile hardware-wallet non-batch EVM flows don’t submit the swap/bridge transaction until the preceding ERC-20 approval tx is confirmed, preventing gas estimation/simulation from running before on-chain allowance is set.

Updates unit tests and snapshots to assert the new waitForTxConfirmation behavior (instead of handleMobileHardwareWalletDelay) and documents the fix in the package changelog.
