feat(mobile): Implement transaction monitoring and indexing hooks

[rafamiziara]

Overview

Create React hooks for monitoring transaction status and triggering immediate pool indexing.

Tasks

Transaction Monitoring Hook

• Create hooks/pools/useTransactionMonitoring.ts
• Implement waitForTransaction() using Wagmi/Viem
• Poll transaction status until confirmed or failed
• Update PendingTransactionsStore with status changes
• Extract poolId and poolAddress from transaction receipt

Pool Indexing Hook

• Create hooks/pools/usePoolIndexing.ts
• Implement triggerIndexing() to call backend indexPool
• Handle immediate indexing success/failure
• Silently fail and rely on scheduled indexing if backend unavailable

Acceptance Criteria

• Transaction monitoring tracks status correctly
• Indexing hook successfully triggers immediate indexing
• Graceful fallback to scheduled indexing on failure
• Proper error handling without blocking user flow
