IAIMantineSelect and IAIMantineMultiSelect have a bit of extra logic that prevents simple select functionality from working as expected.
- extract the styles into hooks
- rename those two components to IAIMantineSearchableSelect and IAIMantineSearchableMultiSelect
- Create IAIMantineSelect (which is just a dropdown) and use it in model manager and a few other places
When we only have a few options to present and searching is not efficient, we should use this instead.
Themes are very fun but due to the differences in perceived saturation and lightness across the
the color spectrum, it's impossible to have have multiple themes that look great without hand-
crafting *every* shade for *every* theme. We've ended up with 4 OK themes (well, 3, because the
light theme was pretty bad).
I've removed the themes and added color mode support. There is now a single dark and light mode,
each with their own color palette and the classic grey / purple / yellow invoke colors that
@blessedcoolant first designed.
I've re-styled almost everything except the model manager and lightbox, which I keep forgetting
to work on.
One new concept is the Chakra `layerStyle`. This lets us define "layers" - think body, first layer,
second layer, etc - that can be applied on various components. By defining layers, we can be more
consistent about the z-axis and its relationship to color and lightness.
