Node debug route

[m0ar]

Adds /v1/admin/debug/:uuid and /v1/admin/debug routes to automatically sanity check nodes.

Does this stuff, among other things:

• validates anchoring
• show anchor timing
• compares db/stream/index versions
• tries resolving dpid alias
• verifies all published manifests have a PublicDataRef

The non-uuid route takes args to search in time over recent activity/node creation, super useful but will result in a ton of activity all over the cluster if not used carefully :p

type DebugAllNodesQueryParams = {
  fromDate?: string,
  toDate?: string,
  timeColumn?: "createdAt" | "updatedAt",
};
