Fix CI failures: missing SC_ERR_GFX, -march=native on WASM, -x c placement

- Add SC_ERR_GFX alias for SC_ERR_BACKEND (was undefined, breaking Vulkan compile)
- Guard -march=native with if(NOT WASM) (unsupported on wasm32-unknown-emscripten)
- Wrap stock_dashboard target in if(NOT WASM) (native Linux executable)
- Move -x c before input file in Vulkan CI compile step
