[Website] Remove obsolete Site Manager UI scaffolding

[adamziel]

This removes Site Manager UI code that no production import path can reach. Keeping it around makes the Dock code look broader than it is and leaves dead full-screen overlay pieces next to the one overlay helper the website still uses.

The branch deletes the old blueprints panel, temporary-site notice, and storage-type components. It also removes the stale TemporarySiteNotice test mock. The full-screen Overlay, OverlayHeader, OverlayBody, PlaygroundLogo, and overlayStyles exports are gone, while OverlaySection stays because SavedPlaygroundsPanel still imports it.

This intentionally does not rename SiteManager, change Dock behavior, alter the open-by-default experiment, or touch the public overlay query parameter.

Verified with:

source "$HOME/.nvm/nvm.sh" && nvm use
git diff --check origin/trunk...HEAD
! git grep -n -E 'BlueprintsPanel|TemporarySiteNotice|PlaygroundLogo|Overlay(Header|Body)|overlayStyles' -- packages/playground/website
! git grep -n 'site-manager/storage-type' -- packages/playground/website
npm exec nx lint playground-website
npm exec nx typecheck playground-website
npm exec nx test playground-website

I also opened the local website and checked the New Playground and Playgrounds panes at desktop and narrow viewport sizes. The pane structure, spacing, empty/current states, and gallery cards matched the expected Dock layouts. The deleted components were not mounted.
