fix: adapt onsite_proj_force_stress.cpp to renamed Plus_U_Base interface

Upstream PR #7873 split onsite_proj.cpp and introduced
onsite_proj_force_stress.cpp, which still called the removed
get_orbital_corr_data() (returning const int*). Our refactor PR had
renamed it to get_orbital_corr_vec() (returning const std::vector<int>&).

Fix by appending .data() at both call sites, matching the new interface.
