Enhance Todo card item textfield with combobox

[karwosts]

Proposed change

Enhance the todo list new item box to autocomplete existing checked items. I thought this was a nice usability improvement, though the code ended up being way more difficult to get exactly right than I initially anticipated, so I can't say for sure if the feature is worth the additional code complexity.
