refactor: rename BorderConfig struct to TableBorderConfig and update option API

- Rename BorderConfig struct to TableBorderConfig for clarity and to avoid naming conflicts
- Update all references, variables, and function signatures to use TableBorderConfig
- Change option function to BorderConfig(cfg TableBorderConfig) for consistency
- Update README and usage examples to reflect new struct and option function names
- Ensure all documentation and code samples match
