Is your feature request related to a problem? Please describe.
Currently, if a variable is missing from var_order_menu it is not displayed in the menu on the web, even if data exists for that variable. This is unintuitive for the user, and hard to debug.

Describe the solution you would like to see
One of the following:

• A log message that indicates the issue and how to solve it (simplest solution probably).
• Automatically add missing variables to var_order_menu (I thought this was how it was supposed to work? Has this changed recently?)
• Solve this on aeroval-web by dynamically discovering variables that should be displayed.
