Refactor simulation types and update imports

- Renamed simulation type imports from `simulation` to `simulationTypes` across multiple files for consistency.
- Consolidated simulation type definitions into a new `simulationTypes.d.ts` file.
- Updated relevant components (e.g., `ArmBot`, `IkInstances`, `PathConnector`, etc.) to use the new type definitions.
- Removed the old `simulation.d.ts` file to clean up the codebase.
- Adjusted function signatures and state management in components to align with the new type structure.
