Chore: Remove unused and redundant gRPC fields

Context:
The codebase contains deprecated gRPC calls and protobuf fields that are no longer used in the communication between the SDK and API. These unused and redundant fields increase the code footprint and may lead to confusion and maintenance overhead.

Tasks:

• Identify all deprecated gRPC calls and protobuf fields in the SDK and API
• Analyze the impact of removing each identified field on the system's functionality
• Create a list of fields that can be safely removed without affecting the system's behavior
• Update the SDK and API code to remove the identified unused and redundant fields
• Adjust any dependent code or references to the removed fields
• Update the gRPC and protobuf definitions to reflect the removal of the fields
• Regenerate the gRPC client and server stubs based on the updated definitions
• Run comprehensive tests to ensure the system functions correctly after the removal of the fields
• Update any relevant documentation, including API specifications and SDK guides, to reflect the changes
• Verify that the removal of the fields reduces the code footprint and improves code clarity
