WebUI: Support auto resizing table columns

[Piccirello]

Auto resize can be triggered by:

1. Double clicking the column's resize handle (its rightmost edge)
2. The table header's context menu

Closes #21627.

In GUI we have "Resize columns" at the bottom of menu.
It will resize all enabled columns. Maybe you would like to match webui with it?

I didn't even realize the GUI had this option. I only added it because users on mobile won't be able to double tap the column edge. For this use case, I think having these options at the top is more useful.

I like being able to resize a single column, but resizing all also seems useful. I'll add a separate "Resize all" action.
