The CLI snapshot test and the headless resize test sent Cmd+Plus to change egui's
interface scale; with the keys handed to View > Zoom they no longer did. A
ui.zoomFactor control request (0.5-3, documented) sets the scale explicitly.

A label added by another PR (Decrease Rating, Display Profile, …) no longer fails the
Ukrainian test; it shows in English until translated, as for the other languages.

Auto was a percentile rule that set Exposure about 1.4 EV higher than
Lightroom's Auto on the same photos (mean +1.81 against +0.44 EV) and
barely used Shadows: on 24 Sony raw photos its results were further from
Lightroom's Auto results (median dE76 22.0) than leaving the photo
unedited (7.9), about 18 L* too bright.
Auto is now Lightroom's shape of rule with values chosen for our results:
- Exposure = -0.58 - 0.41 * the scene's log-average luminance (EV from
middle grey, scene-linear, under the photo's white balance, so it does
not depend on the base tone curve), clamped to -2..3 EV. The slope is
Lightroom's: its Auto's chosen Exposure against our log average, r -0.92;
- Highlights -66 and Shadows +52: Lightroom's own average Auto values;
- Contrast +68 and Vibrance +30 (our scales; our base tone is flatter);
Whites, Blacks and Saturation 0.
The exposure offset, Contrast and Vibrance were fitted jointly so our
renders match Lightroom's Auto exports on the 16 photos whose starting
look Sony's DRO doesn't brighten (#568 changes the other 8). Held out one
photo at a time, each fold fitted from its own training photos only:
median dE76 6.38 on those 16 (8.28 unedited, 18.81 with the old rule),
12 of 16 closer than unedited; 7.70 on all 24 (7.92 unedited); on the 8
DRO photos 9.39 (7.00 unedited), their brighter start showing through.
Freeing Highlights and Shadows too (5 fitted values) did no better held
out (6.51) and left them poorly determined across folds.
The log average skips pixels that aren't finite (a damaged decode) through
the proxy's resampling and white balance; with no valid pixel, Exposure 0.
Values are black-box observations of Lightroom (the settings its Auto
chose and its exports), as in #514. Auto only applies when asked for, so
existing edits keep their look; HDR merges with Auto Settings use the
same rule.
