Answer 1

The node_modules/.bin folder is not in $PATH by default. You need to just call the path directly:
command: /control-panel/node_modules/.bin/ng serve --host 0.0.0.0

Answer 2

It appears sudo is not installed on your image. Note the error message:
"exec: \"sudo\": executable file not found
Something is trying to sudo ("super-user do") a thing, and can't. Try installing sudo via the package manager to appease that step, or try configuring that step to not require super user permissions.
