DX-3089: Add Browser Use to the Connect over CDP page

[alitariksahin]

Summary

• Adds a "Browser Use" section to box/overall/browser/connect.mdx, next to Stagehand, showing how to run a Browser Use agent on the box browser over the CDP URL.
• Names Browser Use in the page intro and in the "Connect over CDP" card on the browser overview page.

Testing

Run against real boxes with browser-use 0.13.10 and upstash-box 0.3.0:

• The snippet as written returned the install command from the quickstart page.
• A multi-step task (navigate, click to page 2, open a story's comments) completed in 4 steps.
• The tab Browser Use ended on was visible through box.browser.list_tabs().
• Both MDX files compile.

The snippet uses claude-sonnet-4-5 because browser-use 0.13.10 sends a forced tool_choice that claude-sonnet-5-5 rejects unless a thinking option is passed.
