fix: normalize Notion recordMap to fix toggles and crashes

The Notion API now returns blocks with nested value.value structure
and role-only entries that crash react-notion-x. Normalize the
recordMap before rendering — skip role-only stubs, unwrap nested
blocks, and preserve all valid blocks including toggle children.
