Fix missing direct includes in cuSolverMp diagonalizer

[Stardust0831]

Summary

• Include the declarations for BlasConnector::copy() and ModuleBase::TITLE() directly in diago_cusolvermp.cpp.
• Normalize the file-ending newline.

This keeps the cuSolverMp translation unit self-contained when ENABLE_CUSOLVERMP=ON. Regular CUDA builds do not compile this source unless that option is enabled.

Build evidence

Before this change:

• Source: f76b1a142c1ac9d3278b9e61a83edb38958c9f5d
• GitHub Actions run 29856565766, build job 88722259940
• Slurm build job 690178: FAILED 2:0
• Compilation failed because ModuleBase::TITLE and BlasConnector were undeclared.

After the equivalent source change:

• Source: f4371be793b082631355727306700dd84efcc229
• GitHub Actions run 29870141313, build job 88768006168
• Slurm build job 690473: COMPLETED 0:0
• The log contains Building ... diago_cusolvermp.cpp.o and ABACUS_BUILD_PASSED.

The overall workflow later reported a separate SDFT numerical test failure; the cuSolverMp-enabled ABACUS build itself completed successfully.
