Type pasted or imported from another app (Illustrator, PDF, SVG) arrives
without cached_bounds, which is not serialized. TextObject::bounds() then
falls back to estimate_bounds(), a rough 0.55 em per character, so the
selection box came up short of the last character and alignment looked off
until the file was saved and reopened (Session::add_document refreshes it).
Refresh the bounds of pasted text in paste_clip, covering paste and paste in
front/back/in place and every clipboard flavour, with a regression test.
