Unblock backend CI by fixing Spotless violations and Pathfinding request arity

[Copilot]

The backend GitHub Actions job was failing in mvn -B test due to Spotless check violations. After those were corrected, a test compile mismatch surfaced in pathfinding tests because PathfindingSimulationRequest calls were still using the old constructor arity.

• Spotless compliance (backend job blocker)

  • Reformatted the exact files reported by CI:
    • backend/src/main/java/com/algorithmrace/visualizer/service/SimulationService.java
    • backend/src/main/java/com/algorithmrace/visualizer/utils/MazeGenerator.java
    • backend/src/test/java/com/algorithmrace/visualizer/controller/SimulationControllerTest.java
  • No functional logic changes; formatting only.

• Pathfinding test compile alignment

  • Updated PathfindingAlgorithmsTest to match the current PathfindingSimulationRequest record signature (10 params, including endCol).

new PathfindingSimulationRequest(
    algorithms, 10, 10, "Clear Grid", null, null, null, null, null, null);
