Fix CI mypy: suppress unused-ignore for env-dependent type errors

- Mypy overrides: warn_unused_ignores=false for modules with
  type: ignore comments that are env-dependent (numpy stubs differ
  between local 3.12 and CI, redis/pymodbus installed on CI but not local)
- Fix hardware_io: read_holding_registers count as keyword arg (pymodbus 3.x)
- Resolves pre-existing CI typecheck failure (since before 69ca883)
