fix: Update port and improve logging

- Change server port from 8086 to 8080
- Use `console.print_info` for logging instead of `println`
- Improve error handling in `decode_generic`
- Update JSONRPC imports for consistency
- Add `console.print_stderr` for not found methods
- Refactor `DBCalendar.list` to remove redundant `println`
- Add `console.print_info` for logging fallback
- Introduce `print_info` in console module for blue text output
