feat: add support for schematic simulation SVG export format

[rushabhcodes]

This pull request adds support for exporting a new "schematic simulation SVG" format in the exportSnippet utility. The changes ensure this new format is properly integrated into the export workflow, including file extension handling and allowed formats.

Support for new export format:

• Added convertCircuitJsonToSchematicSimulationSvg import and integrated it into the export logic in exportSnippet, enabling conversion of circuit JSON to schematic simulation SVGs. [1] [2]
• Included "schematic-simulation-svg" in the ALLOWED_EXPORT_FORMATS array to allow this format as an export option.
• Updated the OUTPUT_EXTENSIONS mapping to provide the correct file extension for the new format (-schematic-simulation.svg).

/fix #1502

Pull request overview

This PR adds support for exporting schematic simulation SVGs, a new export format that enables visualization of schematics with simulation capabilities. The implementation follows existing patterns and integrates seamlessly with the export workflow.

Key changes:

• Imported convertCircuitJsonToSchematicSimulationSvg from the circuit-to-svg library
• Added "schematic-simulation-svg" to the allowed export formats list
• Configured the appropriate file extension mapping (-schematic-simulation.svg)
• Implemented the conversion logic in the export switch statement

you need to setup the simulation engine, we currently use two engines, one is called spicey which is the default, the other is called ngspice which is more mature. you can see how they're setup in core
