fix(delete_profile_photo): pass Photo object instead of int to DeletePhotosRequest

Telethon's DeletePhotosRequest requires InputPhoto objects, which it derives
from Photo objects via get_input_photo(). Passing photo.id (an int) causes:
  AttributeError: 'int' object has no attribute 'SUBCLASS_OF_ID'
  TypeError: Cannot cast int to any kind of InputPhoto.

Fix: pass the Photo object directly (photos.photos[0]) so Telethon can
convert it to InputPhoto internally.
