Make client/server encryption optional, rename tests to full names

Make encryption optional for both ServerRegister's LDS client
connection and the server side of ServerLDS/ServerRegister: when
certificate, privateKey, and trustStore are omitted the programs
run with SecurityPolicy#None only.  Secure servers also add a
discovery-only None endpoint so unencrypted clients can still call
FindServers and GetEndpoints.

Consolidate tests from 5 policy-specific cases (nosec_anon,
none_user, basic256sha256_anon, aes256_anon, aes128_user) down to
3 that cover the important axes: unsecure_anonymous,
secure_anonymous, secure_user.  Rename directories to use full
names.  Auto-generate certificates and trust stores in run_test.sh.

Update readme and CLAUDE.md to reflect the current program
interface (unified Client binary, split ServerRegister configs)
and the new test names.
