[Enhancement]: Create a new API route for updating simulation and connect to the details page

[tomvothecoder]

Is your feature request related to a problem?

No. This enhancement implements planned functionality to support editing and maintaining simulation metadata over time.

Describe the solution you'd like

• Add a new API route to update an existing simulation by ID (e.g. PATCH /api/simulations/{simulation_id}).

• The route should:

  • Support partial updates (PATCH semantics).
  • Validate input using FastAPI request/response schemas.
  • Update audit fields such as last_updated_at and last_updated_by.

• Update the Simulation Details page to:

  • Enable editing of selected simulation fields.
  • Submit changes to the new update endpoint.
  • Display success/error feedback and refresh the displayed data after updates.

• Ensure changes are consistently reflected across:

  • FastAPI schemas (create/update vs. read models as needed)
  • SQLAlchemy models (including constraints and types)
  • TypeScript interfaces/types used by the frontend API layer and UI components

Describe alternatives you've considered

• Deferring edit functionality and keeping simulations immutable after creation.
• Limiting updates to backend-only or admin-only workflows.

Additional context

• This feature completes the CRUD lifecycle for simulations.
• It enables iterative refinement of metadata and supports future enhancements such as change history, permissions, and role-based access control.
• Special care should be taken to keep backend and frontend models in sync to avoid type drift.
