feat: Add CLI table formatting and remove unused inspection methods

- Enhanced CLI output with table formatting for better readability of account and transaction data
- Added new commands to list accounts and view their sync status
- Added new commands to inspect transaction information and cache status
- Cleaned up internal code by removing unused trait methods and implementations
- Updated documentation with examples of new CLI commands

This improves the user experience with clearer CLI output and new inspection capabilities while maintaining code quality.
