Subject: [PATCH] fix(docker): pin frontend builder pnpm to v9

`corepack prepare pnpm@latest` now resolves to pnpm 11, which promotes
ERR_PNPM_IGNORED_BUILDS to a hard error and breaks the frontend stage of
`docker build`. Pin pnpm to v9 to match the CI workflow
(pnpm/action-setup version: 9) and keep image builds reproducible.

Fixes #2442
