columns summed to exactly 100% (e.g. the shipped A4_1.titleblock), this produced qRound(NaN), which fatally aborted under Qt6's stricter qCheckedFPConversionToInteger assertion -- reached via double-clicking a title block template to edit it. Introduce TitleBlockTemplate::classifyWidthConstraint(), shared by minimumWidth() and maximumWidth(), returning std::optional WidthConstraintCase> to distinguish three non-finite outcomes: Unconstrained (RTT columns == 100%, no absolute columns -- an ordinary, valid template), RelativeWidthExceeds100Percent (RTT alone exceeds 100%), and AbsoluteColumnsExceedRemainingWidth (RTT == 100% with at least one absolute column also present) -- the latter two meaning the template's columns cannot be laid out at any width. maximumWidth() previously only checked "are all columns absolute", which incorrectly reported "no upper bound" for the two unsatisfiable cases above; it now shares the same classification, so both functions agree. Update TitleBlockTemplateView::updateDisplayedMinMaxWidth() to show distinct, accurate tooltip text for all four cases instead of printing the old std::numeric_limits<int>::max() sentinel or a misleading "no constraint" message for an unsatisfiable template. Manually verified all four cases: a normal template (finite width), A4_1.titleblock (Unconstrained), an over-100% RTT template (RelativeWidthExceeds100Percent), and RTT==100% with an absolute column present (AbsoluteColumnsExceedRemainingWidth). Translations still partially missing.
