Add data oracle CLI commands for Scenario 23

- Implement store command to save data on IPFS and generate CID
- Implement announce command to publish data availability with price
- Implement listen command to monitor data retrieval requests
- Implement retrieve command to fetch data from IPFS by CID
- Implement listings command to view wallet's data offerings
- Store listings in ~/.aitbc/oracle_data_listings.json
- Update scenario 23 documentation version to 1.1
