fix SDO unit tests for param flags UID change

[Copilot]

The SDO_INDEX_PARAM_FLAGS (0x2200) handler was changed to look up parameters by UID via NumFromId(subIndex) rather than treating subIndex as a direct PARAM_NUM enum index. The flag tests were still sending the enum index (Param::ocurlim = 2) instead of the UID (ocurlim UID = 22).

Changes

• test/test_cansdo.cpp: Update sdo_read_param_flags_default, sdo_write_and_read_param_flags, and sdo_write_param_flags_clear to send Param::GetAttrib(Param::ocurlim)->id as the subIndex for 0x2200 SDO requests instead of Param::ocurlim

// Before
SendSdoRequest(SDO_READ, 0x2200, Param::ocurlim, 0);

// After
SendSdoRequest(SDO_READ, 0x2200, Param::GetAttrib(Param::ocurlim)->id, 0);

The invalid-index tests (sdo_read_param_flags_invalid_index, sdo_write_param_flags_invalid_index) are unaffected — they pass Param::PARAM_LAST (= 3), which is not a valid UID, so NumFromId(3) correctly returns PARAM_INVALID under both the old and new handler.
