Moved configs to flatten directory structure:
- test_extreme_orientation_mixed.toml
- test_extreme_timescales.toml
- test_hybrid_burns.toml
- test_hybrid_energy_conservation.toml
Updated corresponding test files to use new paths:
- test_extreme_orientation_mixed.cpp
- test_extreme_timescales.cpp
- test_hybrid_burns.cpp
- test_hybrid_energy_conservation.cpp
All 240,294 assertions passing in 132 test cases
