FIX: Support Dropbox /scl/ URL format in video and image oneboxes (#38394)
Dropbox has introduced a new sharing URL format using `/scl/fi/` instead
of the legacy `/s/` path. This updates VideoOnebox and ImageOnebox to:

- Detect and transform new `/scl/` format URLs
- Convert to dl.dropboxusercontent.com domain
- Ensure raw=1 parameter is present for direct download
- Maintain backward compatibility with legacy `/s/` format
- Also...added test coverage for both old and new Dropbox formats. All
existing tests continue to pass.
