feat: implement entry management in Bibiman TUI

- Add `.devbox` to the `.gitignore` file
- Create a new backup file `devbox.json.back` with package and shell initialization configurations
- Introduce a new method `add_entry` in the Bibiman struct to manage adding entries
- Implement functionality to handle new entry submissions using `doi2bib`
- Update command actions to include `AddEntry`
- Add `AddEntry` as a new popup type in the TUI for creating entries
- Enhance the UI rendering to support the new entry popup with input fields and cursor positioning
