QFont::toString() is not stable across Qt versions: Qt 6.11 switched to a 19-field format carrying OpenType weights, which QFont::fromString() of Qt 5.x and Qt <= 6.10 rejects, leaving a broken font. Projects saved by a Qt 6.11+ build were therefore unreadable by older builds. Add QETUtils::fontToString() composing the legacy 10/11-field description (weight mapped back to the legacy scale with the same closest-match table Qt uses when parsing) and use it at every site that stores a font description in a project, element, table config or settings file. Every Qt version from 5.15 through 6.12-beta parses this form correctly, so files stay readable by every QET build in circulation. See issue #553.
