Fix: dropzone doesn't receive drop event

[OEvgeny]

Changelog

• Fixed #5390. Fixed drop zone remaining visible when file is dropped outside of the zone, in PR #5394, in PR #5415, by @OEvgeny

Description

While the previous fix (#5394) addressed the visibility issue in certain cases, this PR further improves the drop zone behavior by ensuring it correctly receives outside drop events and handles them appropriately.

Design

1. Added dragover event listener which prevents default browser behavior only when dragged inside the window to prevent unnecessary global event handlers
2. Added detailed documentation explaining the relationship between dragover and drop events

Specific Changes

• Added dynamic dragover event listener management
• Enhanced type definition for dragover event handler to support both React and native events
• Improved comment explaining browser drag and drop behavior
• Reorder listeners

• I have added tests and executed them locally
• I have updated CHANGELOG.md
• I have updated documentation
