refactor: clean up configuration and add production infrastructure

- Add .aitbc.yaml configuration file with test values
- Simplify .gitignore by removing merge conflicts and redundant entries
- Reorganize .gitignore sections for better clarity
- Set chain_id and proposer_id to empty strings in config.py (require explicit configuration)
- Add production Helm values configuration
- Add production nginx configuration
- Update environment variable handling in chain settings
