fix: pin pnpm to v10 in CI and add .npmrc to all frontend projects

pnpm latest on Node 22 resolves to pnpm 11 which rejects lockfileVersion
9.0 lockfiles with ERR_PNPM_LOCKFILE_CONFIG_MISMATCH. Pinning to pnpm 10
keeps compatibility with existing lockfiles. .npmrc sets
strict-dep-builds=false so build-script warnings don't hard-fail the
frozen install.
