Fix WASM duplicate symbols and ranlib conflict

- Remove _IMPLEMENTATION macros from silvercore_wasm target_compile_definitions (sc_kernel.c defines them internally; target-level forces them on stock_dashboard.c too, causing duplicate symbols)
- Add -DSC_SHARED=OFF to WASM CI cmake invocation (Emscripten can't build shared libs; SC_SHARED=ON produced libsc_kernel.a conflicting with static lib target)
