chore: update references from @talos/client to @oplabs/talos-client, …

[toniocodo]

What

Migrates the origin-dollar runner off git-installing @talos/client from the private oplabs/talos repo (SSH deploy key) to the published @oplabs/talos-client GitHub Package. Companion to oplabs/talos#19 (which publishes it) and OriginProtocol/arm-oeth#305.

Changes

• @talos/client → @oplabs/talos-client, declared as an optional peer dependency; the runner Dockerfile installs the pinned version with a read:packages PAT (TALOS_PACKAGE_TOKEN secret). No more SSH deploy key / git install.
• autoInstallPeers: false (pnpm-workspace.yaml + lockfile) so pnpm never tries to resolve the optional peer without a token — token-less pnpm install passes locally, in CI, and in the Docker build.
• Lazy require of the client in contracts/utils/signers.js, behind the DATABASE_URL gate, so hardhat boots when the optional package is absent.
• Dockerfile: # syntax=docker/dockerfile:1.10 (for the env= secret mount) + pnpm add --save-prod.
• @lodestar ^1.41.0 → ^1.44.0 (the one non-obvious change — worth a look): 1.44 drops @lodestar/config's spurious @lodestar/spec-test-util dependency, which shipped a broken vitest: "catalog:" that broke any workspace re-resolution (i.e. the runner image's pnpm add). Net lockfile shrink (~600 lines); retired the now-dead spec-test-util packageExtension.
• Pin @oplabs/talos-client@0.0.28; remove an accidental root pnpm-workspace.yaml / pnpm-lock.yaml.

Validation

• defi.yml green. The failing Base Fork Tests job is pre-existing and non-blocking — it fails on master too and is unrelated to @lodestar (Base is L2, no consensus-layer usage).
• Runner image builds locally end-to-end (frozen install + token-authed pnpm add @oplabs/talos-client@0.0.28).

TALOS_PACKAGE_TOKEN (a read:packages PAT) must stay set on the repo. The image build runs on master; the actual runner roll is a separate signed release.
