Three changes to singlePlayerPage:
1. Store creation no longer waits for isEditorReady. The editor ref
is already passed as optional to NavigationSnapshotService and
loadNodeSnapshotFromDatabase, so we can create and populate the
store without needing the editor to be mounted first.
2. <Tldraw> only renders when store is defined: {store && <Tldraw>}.
Previously it rendered immediately with store={undefined}, which
caused TLDraw to initialize with no backing store and crash
reading topOffset on an unresolved internal object.
3. Loading guard also checks !user so the component never renders
with a null profile before the redirect effect fires.

singlePlayerPage was using useUser().user which is always null (no setter
in UserContext). This caused the redirect effect to always fire, making
the workspace completely inaccessible. Fixed by destructuring profile as
user, which IS properly set from the Supabase profiles query.
Also added 8s timeout to NeoUserContext.switchContext call to match the
NeoInstituteContext timeout fix, preventing infinite spinner if the
navigation API call hangs.
