[REF-3344] Can't paste in big files

[dentro-innovation]

Describe the bug Could it be that it isn't possible to paste very big files?

I got a screenshot that's 2.8 MB.

I can upload it using the "normal" file upload functionality, but when I try to upload this big image, the on_paste handler isn't even triggered.

I do not use max_size of the file_upload component.

To Reproduce Steps to reproduce the behavior:

• Code/Link to Repo:

Expected behavior Being able to upload the same files using the on_drop or paste handler

Specifics (please complete the following information):

• Python Version: 3.12
• Reflex Version: 0.5.7
• OS: linux
• Browser (Optional): firefox, chrome

Additional context Here the screenshot for reference, inside a zip archive to make sure it doesn't get compressed when uploaded to github: big_image.zip
