Remaps Malaysia PLMN (starts with 502) to TEST_FIELD_ROW. The default mapping assigns Malaysia PLMN to APAC_COMMON uecapconfig, which limits LTE to 3xCA and can reduce speeds on networks that support 4xCA/5xCA.
Note: Pixel 6 / Pixel 7 may still hit the 3xCA limit.
Inside NV_PLMN_ID_CATEGORY_MAP, values correspond to PLMN patterns.
For example, category map index 36 refers to 3F,FF,2F,50 → 502FFF3F.
3F corresponds to 63, which maps to APAC_COMMON.
By changing index 36 to 43, the mapping switches to TEST_FIELD_ROW, unlocking the 3xCA limit.
