Restore filetype dep, fix Settings label wrapping to 1px column

python_depends was emptied too aggressively in an earlier fix (dodging
the requests/charset-normalizer Android-wheel bug) and took filetype
with it — kivy/core/image imports it directly, causing a startup crash.
Restored just filetype (pure Python, no dependency chain, safe).

Settings popup's info label set text_size=(self.width, None) at
__init__ time, before layout ever runs — self was the Popup at its
default ~100px pre-layout width, not its real on-screen size, so the
label rendered as a 1-character-wide column. Now binds text_size to
the label's own width so it updates once real layout happens.
