Backend Tests

• Test immediate indexing with valid transaction hash
• Test immediate indexing with invalid/failed transaction
• Test scheduled indexing across multiple blocks

• Test gas estimation and insufficient balance handling
• Test transaction submission and pending state
• Test transaction monitoring and status updates
• Test immediate indexing trigger
• Test pending transaction recovery on app restart
