feat(harfanglab): instance-level tenant scope (1.8.0)

An instance can carry the tenant of the client it serves, for clients sharing
one multi-tenant manager. endpoint_count uses it, for the count and the fleet
total beside it, when the block leaves its tenant filter empty; a tenant named
on the block still wins.
