Add LDAP Distinguished Name Helper and Credential Audit Context

- Implemented LdapDistinguishedNameHelper for escaping RDN and filter values.
- Created AuthorityCredentialAuditContext and IAuthorityCredentialAuditContextAccessor for managing credential audit context.
- Developed StandardCredentialAuditLogger with tests for success, failure, and lockout events.
- Introduced AuthorityAuditSink for persisting audit records with structured logging.
- Added CryptoPro related classes for certificate resolution and signing operations.

+SEC-CRYPTO-90-009 | TODO | Replace the placeholder CryptoPro plug-in with a true CryptoPro CSP implementation (GostCryptography, certificate-store lookup, DER/raw normalization) so RootPack_RU exposes a qualified-signature path. | Security Guild (src/__Libraries/StellaOps.Cryptography.Plugin.CryptoPro)
+SEC-CRYPTO-90-010 | TODO | Introduce `StellaOpsCryptoOptions` / configuration binding for registry profiles/keys and ship an `AddStellaOpsCryptoRu(IConfiguration, …)` helper so hosts can enable `ru-offline` via YAML without custom code. | Security Guild (src/__Libraries/StellaOps.Cryptography + .DependencyInjection)
+SEC-CRYPTO-90-011 | TODO | Build the sovereign crypto CLI (`StellaOps.CryptoRu.Cli`) to list keys, perform test-sign operations, and emit determinism/audit snapshots referenced in the RootPack docs. | Security & Ops Guilds (src/Tools/StellaOps.CryptoRu.Cli)
+SEC-CRYPTO-90-012 | TODO | Add CryptoPro + PKCS#11 integration tests (env/pin gated) and wire them into `scripts/crypto/run-rootpack-ru-tests.sh`, covering Streebog vectors and DER/raw signatures. | Security Guild (src/__Libraries/__Tests/StellaOps.Cryptography.Tests)
