fix(test): update neo4j bolt test to schema v2 :CanNode label

The container-gated bolt test still queried the v1-era :Symbol label,
which no longer exists in schema v2 (every project-owned node carries
:CanNode plus a specific kind label). Since :CanNode spans ALL kinds
(not just the signature-keyed declaration types v1's :Symbol covered),
the exhaustiveness check now enumerates all 11 specific labels that
merge under :CanNode per schema.neo4j.json: Module, Class, Interface,
Enum, TypeAlias, Namespace, Callable, Field, BodyNode, External,
AnonymousCallable.
