feat: support inso global env id / filepath

[jackkav]

motivation: in order to support globals in prerequest scripts when running against a single file export, we would like to load a second file containing global environments.

todo:

• implement
• test
• figure out how importing files would work
• raise active global lookup fetch
• add ws meta support

notes:

• import the global file into the db object, then assign the activeGlobalEnvironmentId in the workspace meta in order for it to be respected by prerequest scripts
• alternatively we could override the env object with the global in prerequest logic
