fix(webapp): let the connected GitHub repo rows size properly in the deploy blank state

The deployments blank state wrapped GitHubSettingsPanel in a shrink-to-fit
container, which was fine for the button-only prompt but not for the connected
repository view now that it renders full-width settings rows. The wrapper
measured 376px against 655px of available space, leaving roughly 88px for a row
label beside its input.

Dropping the wrapper lets the rows use the width the step already has. The
prompt state is unaffected: the button keeps its natural size and only the hint
wraps later.
