chore: pin playwright to 1.58.1 for BrowserStack compatibility

playwright 1.59.x is newer than the version currently supported by BrowserStack's
browserstack-node-sdk codeceptjs integration; sessions launched but never received
WebDriver commands, leading to 120s per-session timeouts. Pinning to 1.58.1 (the
latest BrowserStack-supported release) restores end-to-end execution.

Verified with two clean runs against the patched lockfile:
  - sample-test:       3 passed in 24s  (build 0f982a520e2e9e3bb340f44e211cea81f57e796e)
  - sample-local-test: 3 passed in 18s  (build ee92272577f3ec111596e0dccc67ee1df3118cfc)
