fix: align Playwright runner with dependencies

[Priveetee]

Summary

• align the Playwright runner image with the locked Playwright dependency
• restore Token PO-token and remote-login browser startup

Production behavior

The Token image now ships the Chromium revision required by Playwright 1.63.0. The /potoken route no longer fails because the runner is missing its browser executable.

Deployment requirements

Publish the Token image from main and pin the production token service to its immutable digest. Preserve the current Token image and secret volume as the rollback point.

Runtime verification

• /health returns successfully.
• /potoken?videoId=dQw4w9WgXcQ returns successfully on the built image.
• Existing Token configuration and secret volume remain unchanged.

Tests

• Token CI workflow.
• Docker multi-architecture workflow.
• Local amd64 image build and health/PO-token probe.
• git diff --check.

Rollback

Restore the previous Token image digest and recreate only typetype-token.
