fix(sdk-lib-mpc): use direct dist path for wasm-mps/web import

TypeScript moduleResolution:node cannot resolve package.json subpath
exports like @bitgo/wasm-mps/web. Use the direct file path
@bitgo/wasm-mps/dist/web/js/wasm/wasm_mps for both the type reference
and the dynamic import so tsc resolves it under all moduleResolution
settings.
