ci: workaround npm/cli#4828 for Next build native bindings

The e2e-pr, visual-regression, and e2e-prod jobs build dojolm-web via
`next build`, which loads `next/font` and the @next/swc native binding.
CI intermittently fails with "Cannot find native binding" because npm
ci skips some platform-specific optional deps (upstream bug
npm/cli#4828). The tests job is unaffected because vitest was patched
separately to bypass PostCSS.

Add an `npm install --no-save` step after `npm ci` that explicitly
pulls the Linux x64 gnu bindings for @next/swc, lightningcss, and
@tailwindcss/oxide. `|| true` keeps the step non-blocking if a
package already resolved correctly. --no-save means the lockfile is
not touched.

Long-term fix: regenerate package-lock.json locally on Linux to
guarantee platform native deps are recorded, or switch CI to an
install pattern that handles optional deps reliably.
