Bug description

Hi 👋

In the current release of Expose 3.0.3 the share command’s --auth flag seems broken.

Code reference: ShareCommand::handle() calls ensureExposeSetup() before reading the --auth option.

That means:

1. ensureExposeSetup() aborts if config('expose.auth_token') is empty.
2. Even if I pass --auth=MYTOKEN on the CLI, the command exits with:
   "No authentication token set."

Expected behavior:

• Passing --auth should allow running Expose without needing a config file.
• ensureExposeSetup() should probably run after merging CLI options and config.

Thanks for looking into it!

Steps to reproduce

expose share http://127.0.0.1:5500 --auth=MYTOKEN
> Expose
  No authentication token set.
