[Fix] Correct cid field type to uint16_t to match protocol spec

## Purpose
Fix cid field type mismatch with protocol specification

## Modifications
* Change cid from uint32_t to uint16_t in all Request classes (7 classes)
* Update test cases to use uint16_t for kCid constants
* Protocol spec defines CID as 16 bits [31:16] in Dword 0

## Test
All 11 unit tests passed (7 SQE + 4 link protocol)
