refactor(client-cpp): rename IoTDBDate and move tests

hongzhi-gao · hongzhi-gao · commit 31438de7b726 · 2026-05-27T16:37:11.000+08:00
Rename public Date type from IoTdbDate to IoTDBDate across headers, RPC/session code, and ITs. Move tests from src/test to a top-level test directory and update CMake, Maven, and README paths accordingly.
