Allows users to select logs and copy their contents for debugging, or
pass them on to assistant with one click.
## To test
- go to logs or log explorer
- select some logs
- try copying as json, markdown, or sending it to assistant.
## Context
There's an error from the `LogTable` component `Previous layout not
found` that's caused by trying to set `defaultSize` as a dynamic value
for the `ResizablePanel` component. Theres 2 ways to address this really
Option 1: Set `id` param on `ResizablePanel` to be a dynamic: this came
from a suggestion by the library's author
[here](https://github.com/bvaughn/react-resizable-panels/issues/401#issuecomment-2351010630)
Option 2: Avoid dynamic values entirely
Opting for option 2 as the cleaner way to fix this. Just note as well
that there's a couple of console warnings from the library about
`Invalid layout total size` - this one's safe to ignore and is seemingly
an issue with the current version of `react-resizable-panels` that we're
using (v2, there's currently v4 already)
## To test
Tbh I couldn't reproduce this locally actually, but I happened to come
across this same bug while debugging the `Invalid layout total size`
warning in `DefaultLayout` by trying to set a dynamic value for
`defaultSize` which made me realise the dynamic value was the one
causing that error
