feat(color) - Change Flight Mode list and edit views.

[philmoz]

Fixes #2062

Summary of changes:

• Move trim setup to FM edit page instead of being a popup
• Add trim value display/edit box to FM edit page (only displayed if enabled)
• Display FM list like logical switches, show all FM data for each mode
• Update the trim value range limits in Companion to match the radio

The list view layout is a bit messy; but I'm not sure how to do it any cleaner.
The list view can only handle 6 trim switches at the moment - I hope there aren't any radios with more.

The trim values in the list view will update automatically if the trim is altered via the trim switches (probably need to do this in the edit page as well).

I left the 'Check FM Trims' button at the bottom, although I don't really understand it's purpose. It will however now turn off automatically when the timer runs out.

Wow, great.

Not that I am aware of - or more specifically, none that are supported in code yet. There is another radio that has more trims, but it's not supported yet, so is a non-issue for now.

It's to allow you to check what effect the active FM trims have - FM trims are temporarily disabled.

First of all congratulation for this PR.
It looks already much better and a good step in the right direction.

1. To improve the readability of the FM overview further, an even simpler layout could be welcome by removing the rounded borders around the FM.
   Something like the old overview, and maybe have an alternate light color background. (similar to this screenshot)
   

2. We can also present a FM selection menu instead of having to tap the correct FM directly from the overview list.
   This would allow both high density overview + easy FM selection. Back button is still missing here.
   

3. Another potential improvement from the edit view, would be to add a next / previous selection arrow in the header, to move directly to the next/previous FM settings.
   

Those are only ideas and feel free to discuss/critize them to end up with a beautiful UI !
Thanks again !

I would like to defer any significant changes from the current implementation until later, as there are still some major UI changes ahead as we lead up to 3.0, so all this PR should focus on at present is making the UI more consistent with the rest of the screens, and improving usability, which I think it has achieved. But please continue to make suggestions, the more ideas the better! I particularly like that idea about back/previous arrows in the header - perhaps that is something we somehow consider for any of the edit screens.

I think we should merge this as-is and wait for feedback with 2.9
