[Website] Create stored Playgrounds from URLs or bundles

[adamziel]

Stored-site creation only accepted setup URLs. The Blueprint editor needs to create a separate Playground from its in-memory edited bundle.

Expose createStoredSite() for both inputs. Keep setStoredSiteSpec as the URL-compatible alias. Bundle creation persists the bundle before metadata and removes it if metadata creation fails.

No UI action is wired yet.

Pull request overview

Note

Copilot was unable to run its full agentic suite in this review.

Adds a Redux thunk to create a new OPFS-backed stored Playground from an in-memory, editable Blueprint bundle (intended for future “edited blueprint runs in a new Playground” behavior), ensuring the bundle is persisted before site metadata.

Changes:

• Introduces setStoredSiteSpecFromBlueprintBundle() thunk to persist an edited bundle then create a new stored site entry.
• Adds unit tests verifying persistence order (bundle before metadata) and failure behavior when runtime resolution fails.
• Extends test helper createSiteInfo() to allow custom slug/name to support new test scenarios.
