fix: incorrect paths to CLI resources and files break commands

Some CLI commands are broken due to incorrect paths to resources.
- `postinstall` is broken as the path to common helpers is incorrect. Also we are not injecting correct constants and the generation of `.html` for `test init` command fails. Inject correct constants when generating help.
- `test init` command is broken as path to CLI's resource dir is not correct
