chore: feature tests use sys.executable; sync yarn.lock to package.json

1. AppStarter.start_app() spawned the pgAdmin subprocess with bare
   "python" via subprocess.Popen. macOS (and many modern Linux
   distros) do not provide a "python" symlink — only "python3" or a
   venv-specific binary. The result was an Errno 2 "No such file or
   directory" the moment a feature test tried to launch pgAdmin.

   Switch to sys.executable so the spawned pgAdmin uses the same
   interpreter and venv as the test runner. Works regardless of how
   the venv is named or whether "python" is on PATH.

2. yarn.lock churn from `yarn install` resolving the @tanstack /
   moment-timezone / postcss peer-dep ranges. Snapshot the resolved
   versions for reproducibility (post the dependency bumps in
   d55ffe405).
