Function assertValidNetmap

integration/helpers.go:763–819

assertValidNetmap validates that a client's netmap has all required fields for proper operation. Checks self node and all peers for essential networking data including hostinfo, addresses, endpoints, and DERP configuration. Skips validation for Tailscale versions below 1.56. This test is not suitabl
