docs: add blockchain synchronization verification section

- Add Step 11: Blockchain Synchronization Verification
- Include genesis block verification to ensure same blockchain
- Add height difference monitoring and automatic sync completion
- Include cross-node blockchain data verification
- Add wallet consistency checks across nodes
- Provide success criteria for blockchain synchronization
- Ensure both nodes are operating on identical blockchain data

This section ensures both aitbc1 and aitbc nodes are fully synchronized
and operating on the same blockchain with verification procedures.
