* fix(forms,xfa): find every password field before a save skips scrubbing it The quick Password-flag check in pdfcraft-forms stopped silently at its depth limit, and visited the tree in an order where a field the full field walk reaches could be cut off on a long branch first. It now answers true (read every field) whenever it cannot look as far as the field walk, and also walks below fields adopted from page widgets. XFA password classification walked AcroForm fields only 32 levels deep, shallower than editing and dataset synchronization, and read the datasets packet of an XFA array without the prefixes its preamble declares, so a typed password could stay in the saved datasets. It now walks as deep as the field walk, refuses to clear (and so to save) when the tree is deeper than it can check, and reads the packet the way the datasets writer does. * address review: check every page widget's /Parent chain for the password flag * address review: password scan follows the parents of nameless /Fields entries; field-walk completeness checked before the datasets packet is read * address review: the field walk's completeness is decided after every root; the subtree scan starts at the last dictionary of the parent chain * address review: a skipped visit does not replace the reach a field was classified with
