fix(openclaw): surface tenant headers in remote setup

[Hinotoi-agent]

Summary

• Add accountId and userId prompts to OpenClaw remote-mode setup so root-key users can configure the tenant headers required by tenant-scoped OpenViking APIs.
• Preserve/write those fields in the setup-helper install and upgrade flows.
• Document the root-key accountId / userId configuration in both English and Chinese install guides.
• Add regression coverage for the remote setup wizard saving and defaulting tenant header config.

Fixes #1700.

Why

OpenViking now requires ROOT/root-key requests to tenant-scoped APIs to include X-OpenViking-Account and X-OpenViking-User. The OpenClaw plugin client already supports these headers through accountId and userId, but the supported setup/docs path only exposed baseUrl, apiKey, and agentId. A user following the documented remote-mode setup with root_api_key can therefore hit the reported INVALID_ARGUMENT error after upgrade.

Affected files

• examples/openclaw-plugin/commands/setup.ts
• examples/openclaw-plugin/setup-helper/install.js
• examples/openclaw-plugin/INSTALL.md
• examples/openclaw-plugin/INSTALL-ZH.md
• examples/openclaw-plugin/tests/ut/setup-command.test.ts

Test plan

• node --check examples/openclaw-plugin/setup-helper/install.js
• npm test -- --run tests/ut/setup-command.test.ts tests/ut/client.test.ts from examples/openclaw-plugin
• npm test -- --run tests/ut/setup-command.test.ts from examples/openclaw-plugin
• git diff --check

Note: I also tried tests/ut/config.test.ts, but current main appears to have stale assertions expecting the default mode to be local while config.ts now defaults invalid/missing mode to remote; that failure is unrelated to this patch.
