controllers: fix waveform_zoom ranges

[ronso0]

picked from #12387

updates some old mappings to use the current range 1..10

So far, the code looks correct, but I don't think it is sustainable, because the zoom range is likely to change again.

I think what is missing to do it right, is a JavaScript Engine API function getValueForParameter which does the opposite of:

mixxx/res/controllers/engine-api.d.ts

Lines 65 to 75 in 6acfe63

	/**
	* Normalizes a specified value using the range of the given control,
	* to the range of 0..1
	*
	* @param group Group of the control e.g. "[Channel1]"
	* @param name Name of the control e.g. "play_indicator"
	* @param value Value with the controls range according Mixxx Controls manual page:
	* https://manual.mixxx.org/latest/chapters/appendix/mixxx_controls.html
	* @returns Value normalized to range of 0..1
	*/
	function getParameterForValue(group: string, name: string, value: number): number;

Than we could determine the minimum value for each control by getValueForParameter(<group>, <control>, 0.0) and the maximum by getValueForParameter(<group>, <control>, 1.0).

Thanks, I know that would indeed be much better.
Let's merge this as quick fix and file a feature request for getValueForParameter?

Ok, let's merge it as stop-gap fix.
