fix(test): resolve Metro .web.ts variants in vitest

message-input.tsx imports ./composer-height-mirror, which only exists
as .web.ts / .native.ts / .d.ts. Metro picks the right variant at build
time, but vitest was using Vite's default extension list and failing to
resolve the import — breaking app tests in CI.

Prepend `.web.*` variants to `resolve.extensions` in both the root and
app vitest configs so test runs (which already alias react-native →
react-native-web) pick the web implementation, matching what Metro
does for the web bundle.
