feat: refactor RIB interfaces and update test cases

- Renamed  and  to  and  respectively across various test files and modules.
- Updated response codes in tests to use new definitions ().
- Added new testbench  to validate RIB to RAM interactions.
- Created  for testing RIBP topology routing.
- Adjusted memory map tests to reflect new interface names.
- Ensured all references to old interface names were replaced in Python test scripts.
- Verified that all test cases pass with the new interface structure.
