feat: add Cubox integration for saving entries

Change Summary:
This PR introduces integration with Cubox, allowing users to save entries directly to their Cubox account. Key changes include the addition of new settings for enabling Cubox, configuring an API token, and implementing the backend command to handle the save operation. Several UI components were also updated to accommodate this integration, including localization updates for English and Chinese.

Code Review:
No change requests necessary.

I see that Cubox has two APIs. Do you think adding an option to let users choose whether to save the web page or the content is necessary?

Do you mean the url and memo types? Yes, I do notice the memo option.

The memo type allows users to save a specific part of an article to Cubox, whereas the url type saves the full webpage. However, considering Folo’s mission of gathering resources from RSS and incorporating preprocessing workflows, I see memo as more aligned with fleeting notes or advanced processing, such as annotations, which can later be refined in Cubox or even more systematically in Zotero.

Of course, this is just my perspective. Folo provides an environment for quickly browsing and filtering valuable articles. If an article proves valuable, I prefer saving it to Zotero to retain the full context.

Since I don’t use Cubox in my daily workflow, I’d suggest letting users decide whether to add this option. Alternatively, I can implement it first and gather user feedback to see if it meets their needs.

I've added calls for both APIs. When the memo mode is enabled, clicking the save button will check whether any text is selected — if so, it uses the memo API; otherwise, it falls back to the url API.

As for the SVG of Cubox, I’m currently in touch with their team. For now, it’s using the Eagle icon.

Lastly, here’s a preview.

Thank you very much for what you did, I really like the idea of ​​auto memo mode.

Regarding the icon, I created a simplified version. If the cubox team provides an official icon, I will be happy to replace it, please feel free to create another PR to update it.
