feat: Interactive/progressive preflight checklist (#3564)

* initial version of clickable checklist

* do not display checkboxes for empty lines if checklist is shorter than screen size

* remove checklist exit after completing it
cannot exit menu from menuTextView as level above there is while loop that cannot be stopped from thic place in code

* menu entry to enable and disable interactive checklist

* only when complete interactive checklist is closed

* config updated & not display checkboxes when entered from "View Notes"

* add setup entry for colorlcd

* do not make interactive checkist when loaded from menu

* fix datastruct size after merge

* Companion support for interactive checklist

* mark checklist lines as non-checkable with '=' for B&W radios

* Process only items visible on screen
This is also crucial when it comes to analyse non-checkable items on a checklist, as in this way there is no need to load non-visible items from SD-card

* WIP fix merge problems

* update yaml datastructs

* restore most functionalities for interactive check lists on color LCD radios
currently no automatic line wrapping and you can always exit the checklist, even when it is not fully done

* finalise interactive checklists for color LCD

* fix: rebase/merge issues

* fix: model setup checklist section

* fix: fix 212 model setup

* Re-work of the some of the color lcd checklist code (#3787)

* Move checklist logic to sub-class.
Show model name instead of file name in title, show 'Preflight checks' in title2 for checklist.
Handle long line wrapping of text.
Don't indent lines without checkbox.
Add 'RTN' button when done.

* Code cleanup.

* Simplify code by storing a list of checkboxes instead of scanning LVGL object hierarchy.

* Indent checkboxes to make touch activation easier.
Keep 'RTN' button visible so last checkbox is further from bottom of screen (for touch activation).
'RTN' button is disabled until checklist complete.

* Add checkbox class constructor for preflight checks.

* Fix checkbox size.
