Description

The stream detail page (/streams/[id]) has Withdraw, Top-up, and Cancel buttons but no Pause or Resume. The Stream type already has isPaused and pausedAt fields — the UI just needs the actions.

What Needs to Happen

• Add Pause button (sender only, stream active): call pause_stream() via Freighter, show TransactionTracker
• Add Resume button (sender only, stream paused): call resume_stream(), show TransactionTracker
• Show a "Stream Paused" banner with pausedAt timestamp when paused
• Stop the live claimable counter from ticking while isPaused === true
• Add pauseStream and resumeStream helpers to frontend/src/lib/soroban.ts

Files

• frontend/src/app/streams/[id]/page.tsx
• frontend/src/lib/soroban.ts

Acceptance Criteria

• Pause/Resume shown based on stream state and user role
• Live counter stops ticking when paused
• Signed transaction submitted and confirmed via TransactionTracker
