UI component cleanup

[johnbotris]

We still have lots of old/new component pairs, for example TextField and TextFieldN. We should try to move as many of these duplicates over to just using the new versions.

We also have many components that still used with the pattern:

const component = new MyComponent(a, b, c)

m(component)

We should strive to have all components written like:

m(MyComponent, { a, b, c }

While migrating to typescript (#3746) we will mark calls to m with @ts-ignore as a reminder. This usage of m is not supported by the official mithril TS declarations

Old basic omponents left

• [x] BubbleTextField (w/ embedded TextField)
• [x] Button
• [x] Dropdown
• [x] DropdownSelector
• [x] Header (needs to be re-done?) Note 14/02/2023 - SearchBar is closely tied into Header and really needs a deep rewrite for header and itself to have the new component structure. Would need to discuss how Header and SearchBar should interact, and what parts of SearchBar should be moved into SearchModel or into new Search functionality. Should be made into its own issue.
• [ ] SearchBar
• [x] InfoView (used in one place)
• [x] List (big change)
• [x] Table/TableLine (used in one place)
• [ ] ViewSlider/ViewColumn (might be a big change)
• [ ] Editor (big change)

Many of them could be removed with settings redo (#47).

There are also unused components? I don't think they need to be kept around if we aren't using them:

• NavBarN
• LabelN

Maybe more

Edit: this is handled
