…1563) (#1630)

Cherry-pick of #1563. Also added a few lines from #1365 that were needed to make this work

* Previously, key columns containing non-numeric types would display
`null` is the rolled up rows have different values for the same column
    * This behaviour is updated to show an empty cell instead of `null`
* Resolves #1483 

#### Testing Instructions:
1. Run: 
```python 
from deephaven import empty_table, time_table
  
  size = 100
  scale = 1000
  
  random_values_with_null_NaN = empty_table(size).update([
      "MyString=(i%11==0? null : `a`+(int)(scale*(Math.random()*2-1)))"
  ])
```
2. Add the string and char columns and any other arbitrary columns as
rollup columns in any order
3. The key column should only show `null` if it actually represents a
null value in the column

Chrome adopted offical support for scrollbar-color in chrome 121.
However, if you have both scrollbar-color and ::webkit-scrollbar
styling, they conflict and chrome will only honour the native styling.
This is bad because the native chrome mac scrollbars become really
small, and overlap too much with out golden-layout drag.

Our webkit styling forces scrollbars that match monaco and grid, and are
preferred. By removing `scrollbar-color` native styling, our webkit
styles work. We only had scrollbar-color to style firefox in dark mode
(`//applies to firefox only` is no longer true), however the most recent
versions of firefox appear to color scrollbars automatically based on
the theme, so this is no longer necessary.

The crappy part here is since this is browser change, we will have to
backport this for several active enterprise versions.

- Fix adding error console history items
- They weren't appearing as anything because the command was `''`
instead of `undefined`
- Map LOCAL_TIME to STRING on CSV import
- `LOCAL_TIME` isn't supported on the server in DHC, and isn't really
"safe" anyways since we should have other info in there as well (e.g.
date or time zone)
- When exporting, should be exporting the 'unformatted' value, which
gives you the full timestamp
- By mapping to String, user can then do an `.update_view` to map it to
a timestamp if they wish
- Fixes #1432
- Cherry-pick back for DH-15013. Tested against dev-vermilion.
