[ENH] Improve finite-fault and grid scalar handling with backend adjustments and test updates

[Leguark]

Refactor scalar handling for finite_fault_scalar to ensure compatibility with numpy and tensor backends. Introduced additional NumPy array safeguards, resolved dtype inconsistencies, and updated dependent tests for clarity and stability. Enhanced test coverage with conditional skipping for backend-specific implementations and stricter validation for interpolation workflows. Updated environment defaults for headless test runs.
