Generate protobuf code for TypeScript service - Frontend

[Sozhan308]

Changes

Part of #1787 to generate profobuf files for all services.

This PR implements pre-generation of protobuf definitions for the frontend service

1. Created a dedicated Dockerfile for protobuf generation

   • Added src/frontend/genproto/Dockerfile for handling proto generation

2. Updated main frontend Dockerfile

   • Removed protobuf generation from build stage
   • Added pre-generated protos copy
   • Removed unnecessary protobuf dependencies from runner stage

Testing

• Verified proto generation using docker-gen-proto.sh
