Fix test_hybrid_impulse_burns to use maneuver system

- Added helper functions: find_maneuver_by_name() and execute_maneuver_by_name()
- Modified Hohmann transfer test to use maneuver system via execute_maneuver()
- Modified large burns test to use maneuver system
- Modified energy conservation test to use maneuver system (prograde burn)
- Modified round-trip conversion test to use maneuver system
- Modified multiple burn sequences to use maneuver system for Hohmann transfer
- Tests now properly validate maneuver trigger and execution workflow
- All tests pass (96 assertions in 7 test cases)
