Rename RawKvPair to RawKVPair for protobuf naming consistency

[Copilot]

Addresses naming inconsistency in protobuf definitions where RawKvPair used mixed-case acronym style while the service name RawKV and other messages follow the convention of treating acronyms as single words.

Changes

• proto/service.proto: Renamed RawKvPair → RawKVPair message definition
• adapter/grpc.go: Updated type references to pb.RawKVPair
• Regenerated all protobuf Go code with updated naming

// Before
message RawKvPair {
  bytes key = 1;
  bytes value = 2;
}

// After
message RawKVPair {
  bytes key = 1;
  bytes value = 2;
}

This aligns with the existing RawKV service name and standard protobuf conventions.

Pull request overview

This PR renames the protobuf message RawKvPair to RawKVPair to achieve consistent acronym casing throughout the protobuf API definitions. The change aligns the message name with the RawKV service name, treating "KV" as a single acronym unit rather than mixed-case "Kv".

Changes:

• Renamed protobuf message from RawKvPair to RawKVPair in proto/service.proto
• Regenerated all protobuf Go bindings with updated protoc toolchain (protoc v3.21.12, protoc-gen-go v1.36.11, protoc-gen-go-grpc v1.6.1)
• Updated adapter/grpc.go to reference the renamed type pb.RawKVPair
