test: expand MeshImporterExporter coverage

[fernandotonon]

Summary

• Add 16 integration tests in MeshImporterExporter_test.cpp covering previously untested import/export branches.
• Exercise PlayStation TMD/RSD and Psy-Q PLY import via MeshImporterExporter::importer, FBX/TMD/RSD/STL/GLB/versioned .mesh export, applyNormalMapsToEntity (tangents + RTSS), skeletal exportCurrentPose, XML skeleton export, and camera FOV edge cases.
• Use inline minimal PS1/TMD/PLY fixtures (no new test assets); avoid tests that block on QMessageBox in headless CI.

Test plan

• xvfb-run ./build_local/bin/UnitTests --gtest_filter on all new tests (16 passed)
• CI unit-tests-linux on PR
