fix: ODT indexes and shape boxes read back clean

The TOC importer no longer fabricates settings our own export mints: a right
stop at the column's end is the attr's default (null), and an entry template
resolving to the default style names no levelStyles entry. A custom-shape box
keeps its vertical text (the writing-mode read only ran for plain frames),
and a declared all-off tableLook ('') survives instead of reverting to the
default look.
