Subject: [PATCH] fix(auth): configure OpenClaw default model when saving
 provider

- Add setOpenClawDefaultModel() to write the correct model to
  ~/.openclaw/openclaw.json based on the selected provider
- Maps: openrouter -> openrouter/anthropic/claude-sonnet-4,
  anthropic -> anthropic/claude-sonnet-4, etc.
- Call setOpenClawDefaultModel on provider:save IPC handler
- Fixes "No API key found for provider anthropic" when user
  configured OpenRouter (wrong default model was being used)
