Add tests for files in file-explorer. Note: Drag and drop is not tested.

- Pulled the types out of `jsapi-shim` into a separate pacakge
`jsapi-types`
- Now other packages can import just the types without the shim possibly
failing because the API isn't loaded yet
- Will be deprecated/replaced with the automatically published TS
definitions when @niloc132 has finished that
- Added `jsapi-bootstrap` package to load the API and display an error
if it can't load
  - Can set the API globally, or use it from a React context object
  - Displays an error if the API cannot be loaded
- Use code-splitting to bootstrap the API globally to keep existing code
running until we port everything over
- We should now look at completing deephaven#444 , and get rid of the
`embed-grid` and `embed-chart` packages. We can now code-split at the
top level.
- Enabled proxy in both embed-grid and embed-chart, keeping the loading
similar between all three apps
- Requires change deephaven/deephaven-core#2733

Breaking Change: The JS API packaged as a module is now required for the
`code-studio`, `embed-grid`, and `embed-chart` applications. Existing
(Enterprise) applications should be able to use `jsapi-shim` still and
load the JS API using the old method.

Enterprise uses golden-layout hasHeaders: false in layout config for
query monitor. A check added as part of typescript conversion was
preventing headers from being set to display none when it was false
(toggle is a jquery method that hides/shows based on a boolean).

- isDragging was always set to true on itemMouseMove which prevented
onSelect from firing on even the slightest of mouse movements while
clicking
- Set isDragging to true only if the mouse moves at least 5 viewport
units in the X or Y direction between the mouseDown and mouseUp events
(attempted to get this value as close as possible to when the UI changes
to indicate dragging)

Conditional formatting for date columns now properly prevents conditions
with empty values from being applied.

…phaven#1117)

deephaven/deephaven-core#3385 is a port of DH-11692 which adds `Instant`
and `ZonedDateTime` support to the engine. I've similarly encoded these
types over Barrage as a `long` (as a nanosecond since epoch). The
encoding of Zones will actually need to be implemented at a future date
as the best implementation requires (encourages?) a much larger
refactoring of ColumnSource types. See deephaven/deephaven-core#3455 for
more information.

I was able to get the web-client-ui to display these types with this
small patch.

I asked chatGPT to help me brainstorm improvements to some of the labels
and hint text based on the Apple Human Interface Guidelines. I then
edited them as human to improve them further.

Review and let me know if you think any are worse or weird.

Fixes deephaven#1027 
- `null` values are not supported by the API, so it is not implemented

- Styleguide index wasn't updated to use JS API as a module correctly

- User is expecting the plots to be ordered 0 at top, increasing
downward
- Plotlys bounds coordinate system has 0,0 in the bottom left,
increasing upward
- Invert the coordinates so that it appears in plotly correctly
- Add unit tests
