Default value filling for numbers OGC extension

[grallewellyn]

Using the ogc image in the staging hub, there's a bug in the logic that loads an existing yaml file for algo registration: when an input is a numeric type, and the default value is "falsy" (e.g., 0 or 0.0), the default value is not populated in the default value box in the UI. However, if the falsy default numeric value within the the yaml file is enclosed in double quotes, or a non-falsy (non-zero) numeric default is specified, the UI is properly populated. Using quotes should not be required.
