Empty file upload

[yenienserrano]

Description:

When trying to import an empty file in rules or decoders, there was no information, it let you upload it but it had no effect, I added a warning to let the user know that he is uploading an empty file and not to let him upload it.

Test:

1. Navigate to Management/rules or decoders
2. Try uploading an empty file
3. See the warning

Issue:

• No error message is displayed when uploading an empty file #4059

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add .worktrees/backport-4.3-7.16 4.3-7.16
# Navigate to the new working tree
cd .worktrees/backport-4.3-7.16
# Create a new branch
git switch --create backport-4176-to-4.3-7.16
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 82003767adabc6b0f59bbb94b91d5ec8fb5b3638
# Push it to GitHub
git push --set-upstream origin backport-4176-to-4.3-7.16
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-4.3-7.16

Then, create a pull request where the base branch is 4.3-7.16 and the compare/head branch is backport-4176-to-4.3-7.16.
