fix(spaces): default visibility to private (sovereign by default)

Spaces with missing/undefined visibility were falling through to "public"
in 7 places: normalizeVisibility fallback, migrateVisibility early return,
renderShell default, getSpaceConfig, space list APIs, and the HTML
injection middleware. All now default to "private". The migrateVisibility
function now writes "private" to docs with missing visibility on load.

Also fixed jeff and hash spaces on production (were undefined → private).
