Audit of post-fork param additions found CarCruiseDisplayActual was written every CAN cycle (gated) but only consumed by hyundaicanfd.py:: create_buttons_alt, which has `return` on line 1 and no active callers. Write was pure waste. Removed registration, write path, cache field, and the dead read. Also dropped the now-unused `from openpilot.common.params import Params` in hyundaicanfd.py.
