refactor: normalize remaining uppercase filenames to lowercase (phase F)

Rename 44 files, converting uppercase letters to lowercase:
- Cblacs.h → cblacs.h
- cal_pLpR.{cpp,h} → cal_plpr.{cpp,h}
- cal_r_overlap_R.{cpp,h} → cal_r_overlap_r.{cpp,h}
- ewald_Vq.{h,hpp} → ewald_vq.{h,hpp}
- ExxLriDetail.{cpp,h} → exx_lri_detail.{cpp,h}
- Exx_LRI.{h,hpp} → exx_lri.{h,hpp}
- Exx_LRI_interface.{h,hpp} → exx_lri_interface.{h,hpp}
- fR_overlap.{cpp,h} → fr_overlap.{cpp,h}
- Inverse_Matrix.{h,hpp} → invmat_ri.{h,hpp}
- opt_TN.hpp → opt_tn.hpp
- single_R_io.{cpp,h} → single_r_io.{cpp,h}
- symmetry_rotation_R{,_hcontainer}.hpp → symmetry_rotation_r{,_hcontainer}.hpp
- write_dH{,_terms}.{cpp,h} → write_dh{,_terms}.{cpp,h}
- write_HS{,_R,_sparse}.{cpp,h} → write_hs{,_r,_sparse}.{cpp,h}
- write_H_terms.{cpp,h} → write_h_terms.{cpp,h}
- pw_basis_{C2C,C2R}.cpp → pw_basis_{c2c,c2r}.cpp
- pw_basis_k_C2C.cpp → pw_basis_k_c2c.cpp
- test_T_NL_cd.cpp → test_t_nl_cd.cpp
- test-{big,other}.cpp → test_{big,other}.cpp
- test_hcontainer_readCSR.cpp → test_hcontainer_read_csr.cpp
- test_{cal_dm_R,dm_R_init}.cpp → test_{cal_dm_r,dm_r_init}.cpp

Update all #include references, CMakeLists.txt, Makefile.Objects,
CMake target names, and code comments. Class names, function names,
namespace names, and header guards preserved unchanged.
