docs: refresh media assets, embed setup screenshot, promote downloads badge

[elkaix]

Summary

• Regenerate docs/media/shell-mode.gif from a new recording (ffmpeg palette pipeline, 860px/10fps, 3.1 MB) and refresh docs/media/setup.png
• Embed the setup screenshot (login provider picker) in the README Authenticate section
• Promote the PyPI downloads badge to the primary badge row using the shields.io pepy endpoint (for-the-badge style)

Docs/media only — no shipped code paths touched, so no changelog entry is required.
