Add complete OAuth token refresh and sync solution

- Setup wizard with auto-detection of OpenClaw paths and Claude CLI
- Token sync watcher (inotifywait) for real-time credential updates
- Auto-refresh trigger timer that runs Claude CLI every 30 min
- Supports Claude CLI in Docker container or on host
- Temporary ANTHROPIC_BASE_URL override for container environments
- Anthropic model configuration for OpenClaw
- Auth profile management (fixes key vs access field)
- Systemd services and timers for both sync and trigger
- Comprehensive documentation and troubleshooting guides
- Re-authentication notification system
