fix(accounting): align protobuf file paths with make target (#2390)

* fix(accounting): align protobuf file paths with make generate-protobuf target

The accounting service protobuf configuration was inconsistent with the
gen_proto_dotnet function used by the make generate-protobuf target.

Changes:
- Update Accounting.csproj to reference protobuf files at src/protos/demo.proto
  instead of proto/demo.proto to match gen_proto_dotnet output location
- Update Dockerfile to copy protobuf file to Accounting/src/protos/demo.proto
  to align with project file expectations
- Update README.md local build instructions to use make generate-protobuf
  instead of manual file copying commands

* Update README.md
