Implement optimistic UI updates so stream list reflects changes before confirmation

[Chuks-coderr]

Overview

Currently, UI state only updates after a transaction is confirmed on-chain, which takes several seconds. Optimistic updates show the expected post-confirmation state immediately, making the UI feel fast and responsive.

Problem

After submitting a withdrawal, the UI shows a loading spinner for 5-10 seconds until confirmation. Users cannot see any feedback that their action was recorded, leading to double-submissions.

Proposed Solution

• Implement optimistic updates for: withdraw (immediately decrement claimable balance), cancel (immediately remove stream from list), top-up (immediately update stream end date)
• Roll back the optimistic state if the transaction fails
• Show a subtle Confirming... indicator alongside the optimistic state

Acceptance Criteria

• Stream list reflects the withdrawal immediately without waiting for confirmation
• Failed transaction rolls back the optimistic state and shows an error toast
• Confirming indicator is visible during the on-chain wait
• Multiple concurrent operations do not conflict in optimistic state
• E2E test verifies optimistic update and rollback behaviour

Hi Maintainer, I'd like to work on this issue. I have experience handling similar tasks and can start immediately.

I'll add optimistic updates for the withdraw, cancel, and top-up actions, decrementing the claimable balance, removing the stream, and updating the end date immediately, with automatic rollback and an error toast on failure, a subtle "Confirming..." indicator during the on-chain wait, and an E2E test covering the optimistic update and rollback flow.

Please assign it to me.
