tscap now anonymizes captures at write time (see kradalby/tscap
package anonymize): SaaS user identifiers become odin/thor/freya and
node hostnames become original-151 pokemon names. Update the four
policy v2 compat test setups to construct types.User and types.Node
objects with the new names so the in-test topology matches what the
captured testdata files contain.
The convertPolicyUserEmails / convertSaaSEmail helpers become
passthroughs because tscap already produces the final email form.
