Grinder setting up down button that navigating through the known values

I have contemplated your suggestion about using dclicker on discord chat. However, I could not figure out the generally suitable solution. So...... I'm just submitting this PR.

Here, I would illustrate my thoughts:

• Grinder setting is a string, and dclicker provides numpad. It is inconvenient to edit the string through the on-screen numpad. For example, minus numeric value(no +/- botton on the numpad), settings with alphabet chars like forte, or someone maybe describing the grinder speed in some arbitrary form, like 1.3@1600, ...
• Most people, at least I think, would have enough history of shots to generate their all-time used popular settings. So, I thought that the "navigating through the known values" would be more convenient when doing a dialing-in.
• Yes, yes, these buttons are not the magic solution for making the adjustment more convenient. It may even confuse some people with non-numeric settings. but...
• If the navigating direction of the up/down button is same as the order of the items in the selector screen, it could be quite useful.

This PR includes:

• Up/down button navigation (following the order in the selector screen)
• Sorting the settings if they are all numeric values (if it fails, it fall backs to the original order, order by grinder_setting sql clause.)
• Pre-populating the known grinder settings on DYE screen loading, only once, not on poping up the selector screen. This also applies for the selector screen.
