Walkthrough

This pull request enhances file upload handling across several components. The changes introduce an optional file name property, update function signatures to accept nullable files, adjust state management for file names, and modify modal workflows to include navigation refreshes. The repository method now conditionally appends files, and modal actions have been refined to prompt for file save or deletion, ensuring robust handling of file operations.

Poem

I'm a rabbit with a joyful hop,
Changes in code make my heart non-stop.
Nullable files now gracefully play,
In modals and repos, they're led the way.
With a twitch of whiskers and a cheerful beep,
I celebrate code that hops to a leap!
🐇🎉

  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
