[Copilot]

• Rename HashProvider::Hash to HashProvider::hash in base class (include/ccf/crypto/hash_provider.h)
• Rename OpenSSLHashProvider::Hash to OpenSSLHashProvider::hash in subclass (src/crypto/openssl/hash.h)
• Update all call sites (7 usages across crypto and RPC code)
• Verify build compiles successfully
• Add CHANGELOG.md entry under 7.0.0-dev10 → Changed section (Rename HashProvider::Hash to HashProvider::hash #7660)
