Persist Left Panel Resize

[arniebradfo]

Description

Give the text content in the left panel more room for readability.

• Left Panel is now a bit larger by default - 600px
• Left Panel now persists its resize between page reloads using window.localStorage
• The drag resize now more precise
• css grid layout is simplified
• Double clicking the dragger will reset the left panel to the default size
• I made a commit that persists the collapsed state of either panel, but the graph does not initialize properly if the panel its in starts collapsed. I reverted that change and left a note.

Testing

• drag resize the left panel
• reload the page

@arniebradfo I found a bug where if we refresh the page after resizing the left panel, the command log output disappears.
