Walkthrough

Updated the zoom status text display in the custom title bar of the QML interface. When zoom ratio is within ±0.03 of 1.0, the display now shows "Zoom: Fit to window (%)" instead of just "Fit to window". Other zoom levels now prefix with "Zoom:" and round the percentage value.

Cohort / File(s)	Summary

Use one zoom basis for both fit and non-fit labels

This change mixes two different percent bases in the same label: the fit branch shows absolute scale (zs * 100), while the non-fit branch shows relative-to-fit scale (ratio * 100). When currentFitScale is not 1.0 (common on large images), a tiny zoom change across the 3% fit threshold can make the title jump from something like Fit to window (42%) to Zoom: 104%, which is misleading because the underlying zoom barely changed. Keeping both branches on the same basis avoids this discontinuity.
