qet-mcp: a symbol's own texts are not free texts on the folio

qet_diff's texts, shapes and pictures sections collected every <input>,
<shape> and <image> under a folio with iter(). Symbols in older files carry
their own <inputs><input> texts, so those were counted as the folio's free
texts: schema_indus.qet folio 1 showed 124 where QElectroTech has 2, and
editing one of those symbol texts would have been reported as a free text
changing.

Only the folio's direct <inputs>, <shapes> and <images> children are read
now. Shapes and pictures have no nested copies in the shipped examples;
they are changed too so the three stay alike. Found by comparing the
tools' answers with QElectroTech's own lists over the shipped examples.
