fix: force onnxruntime-web@1.18.0 via resolutions to eliminate nested 1.24.3

vad-web's own dependency was resolved to ort@1.24.3 (nested in its
node_modules), which only has threaded WASM requiring a .mjs dynamic
import that Vite fails to serve correctly. Pin ort to 1.18.0 via yarn
resolutions so all packages share the same copy with ort-wasm-simd.wasm
(non-threaded SIMD). Also remove the now-unnecessary COOP/COEP headers.
