fix: Add .delta suffix fallback for delete_object()

- delete_object() now tries with .delta suffix if file not found
- Matches the same fallback logic as download/get_object
- Fixes deletion of files uploaded as .delta when user provides original name
- Add test for delta suffix fallback in deletion

This fixes the critical bug where delete_object(Key='file.zip') would fail
with NotFoundError when the actual file was stored as 'file.zip.delta'.

Now delete_object() works consistently with get_object():
- Try with key as provided
- If NotFoundError and no .delta suffix, try with .delta appended
- Raises NotFoundError only if both attempts fail
