Fix cd cancel and cd refresh

[lionello]

Description

Failures in CLI:

$ defang cd cancel --project-name nextjs -Pdigitalocean
 * Using DigitalOcean provider from command line flag
 * Running CD command "cancel" in project "nextjs"
Error: invalid image:

AWS:

$ AWS_PROFILE=defang-lab defang cd cancel --project-name nextjs -Paws
 * Using AWS provider from command line flag
 * Running CD command "cancel" in project "nextjs"
Waiting for CloudFormation stack defang-cd to be updated...
Error: waiter state transitioned to Failure

Getting empty image URL even though I’m pro. Seems that cancel and refresh didn't check canIUse.

Missed these two commands in #929
