QFont::fromString() of Qt 5.x and Qt <= 6.10 rejects the >= 19 field descriptions QFont::toString() emits since Qt 6.11, silently leaving a broken font at every read site. Add QETUtils::fontFromString(): try the native parser first, and on failure re-compose the legacy 10/11 field form from the known Qt 6.11 field layout (OpenType weight mapped back to the legacy scale) so no font information stored in existing files is lost. Also salvage the 21 field double-serialized descriptions left behind by some historical builds (a complete legacy description embedded as the family name of a second one) by taking the embedded leading description, matching what the lenient parser of Qt 6.11+ resolves them to. All font read sites now go through the helper; on failure the default font of the caller is left untouched instead of a cleared family. Verified end to end on a Qt 5.15 build: a project whose 53 font attributes were rewritten into the 19 field Qt 6.11 format loads and autosaves byte-identical to the original legacy file (family, sizes, bold/italic/underline, style name all preserved), and a mixed file containing the exact 21 field string from the issue comes back normalized as "Caladea,9,-1,5,75,1,0,0,0,0,Bold Italic". See issue #553.
