Open auth browser without keypress prompt

[gonzaloriestra]

WHY are these changes introduced?

Fixes https://github.com/shop/issues-develop/issues/22867

The login flow currently pauses in interactive terminals and asks users to press a key before Shopify CLI opens the browser. We want authentication to start directly by opening the browser, making it easier for agents.

WHAT is this pull request doing?

• Removes the keypress() wait and "Press any key" message from the interactive device auth flow.
• Keeps the existing manual-link fallback when the browser can't be opened.
