#743: freeforms in groups keep their shape; text boxes keep their margins and Resize to fit (#843)

A Word 365 cover page lost its look. The missing fills came from theme-coloured shapes (scheme colours and wps:style fill references), which the reporter's 0.5.0 build didn't read; #611 fixed that on main. Two causes were still open on main: - A freeform (a:custGeom) inside a wpg group was drawn as a rectangle. read_wsp now reads custom geometry, so group members get it as well. - Text boxes ignored wps:bodyPr lIns/tIns/rIns/bIns and a:spAutoFit. Layout always used Word's default margins, so a title box with no margins that was just tall enough for its text lost its second line. TextBody now carries the box's own margins and auto_fit. Layout uses those margins and doesn't cut the text of a box that resizes to fit. Both are written back on save.
