fix: sync node and activities after a successful boost

[jvsena42]

Description

This test fails randomly in android for two reasons:

1. RBF -> Returns to home before the new transaction is displayed -> intent to selected the new transaction created after boost but click in the old transaction instead -> Await for the boost button update to "boost finished" but the transaction updates to "removed from mempool instead
2. If not fail on the previous step, the automation try to return to the Home Screen from the drawer, but the app displays a "transaction removed from mempool" toast and the CI timeouts trying to find the drawer button

The iOS app don't fail because:

1. After boost, it performs LDK node and activity syncs before returning to home
2. The "Transaction replaced" toast is replaced immediately by the boost success toast

Solution:

1. After successful boost, perform LDK node and activities sync (may increase the operation time for wallet with many transactions)
2. For toast:
   2.1. Cancel autohide like iOS (I'll try this solution first, but UX wise, I'd prefer the current logic of keeping the delay between toasts)
   2.2. Or remove "Transaction removed from mempool" toast, because it doesn't exists in the figma
   2.3 Or increase the timeout of the test action, or update it to dismiss the toasts

Pull request overview

This PR fixes a race condition in the boost transaction flow that was causing random test failures in Android. When a transaction is boosted via RBF or CPFP, the app now properly syncs the Lightning node and activities before completing the operation, and immediately dismisses any existing toasts to prevent the "Transaction removed from mempool" toast from interfering with the "Boost successful" toast.

Key changes:

• Added Lightning node and activity sync after successful transaction boost
• Changed toast queue behavior to immediately dismiss current toast when showing a new one
