test(web): catch experimental-edge in the edge-runtime scan

The scan matched only `export const runtime = "edge"` in .ts/.tsx files.
It now also matches `experimental-edge` and `runtime: "edge"` object
forms, and scans .js/.jsx/.mjs files under app/.

Test: product-telemetry-route.test.ts 3/3 (1 new; failed with the old
pattern on experimental-edge).
