DAD wavelengths are incorrectly called traces in the overlay

[Mailaender]

This is somehow in between wrong and a polish problem. DAD wavelengths aren't traces which is confusing wording and the defaults like column bleeding mass traces from GC don't make any sense in LC-DAD scenarios. Someone who uses MS and DAD detectors at the same time might want to save user-defined settings for both without switching all the time in the chromatogram overlay.

Internally, the term "trace" is used as a generic placeholder for m/z values or wavelengths. We should keep it internally as trace. But you're right, the front end labels might make a differentiation.

Even internally it is called wavelength as far as I see:

Yep, correct :-).

The layer on top, especially used in the template processor, uses "trace" as a synonym.
A ticket, which is also in progress, is worth to be mentioned here:

Trace wavelength is a term in acoustics https://asastandards.org/Terms/trace-wavelength/ but not in analytical chemistry.
