*	Move certificates into per-test directories	Thomas Vanbesien	37 hours	1	-20/+2
\| \| \| \| \| \| \| \|	Each secure test now has its own certs/ subfolder with per-identity subdirectories and a single shared trust store. Configs reference paths relative to the project root (e.g. tests/secure_anonymous/ certs/ServerLDS/cert.der). Cert generation logic removed from test scripts since certs are now pre-generated and committed.
*	Add download-cert client operation with integration test	Thomas Vanbesien	37 hours	1	-0/+114
	Retrieves the server's DER certificate via GetEndpoints and writes it to a local file. The test starts a secure ServerLDS, downloads its certificate, and verifies it matches the original.
