*	Extract createUnsecureClientConfig, fix None endpoint negotiation	Thomas Vanbesien	39 hours	3	-13/+2
\| \| \| \| \| \| \| \| \| \| \| \|	UA_ClientConfig_setDefault leaves securityMode at SignAndEncrypt, so unsecure clients failed endpoint negotiation when the LDS only offered None endpoints. Extract the unsecure client setup into createUnsecureClientConfig() which explicitly sets securityMode and securityPolicyUri to None. Also enable discovery-only None endpoint on ServerRegister so unencrypted clients can discover it, and update the unsecure_anonymous test configs to run fully without encryption.
*	Add None endpoint so unsecure clients can discover secure servers	Thomas Vanbesien	42 hours	1	-4/+0
\| \| \| \| \| \| \| \| \| \|	UA_ServerConfig_addSecurityPolicyNone only adds the security policy, not an endpoint entry. Without a None endpoint in the GetEndpoints response, the open62541 client's internal endpoint negotiation fails with BadIdentityTokenRejected before the FindServers request is sent. Adding the endpoint via UA_ServerConfig_addEndpoint makes the None endpoint visible; securityPolicyNoneDiscoveryOnly still restricts it to discovery services only.
*	Make client/server encryption optional, rename tests to full names	Thomas Vanbesien	44 hours	4	-0/+49
	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.
