docs: the hive has no approval queue

config-changes.md (was approvals.md) describes config PRs, the meta flake
and helper events; the approval queue, its kinds, the withdraw path, the
job-queue dispatch and ApprovalResolved go. Every other page drops the
approvals table, endpoints, event, tool group, hivectl verbs, dashboard
section and the loose-end/cancel kind, and links to the renamed page.
