Fix CodeQL security vulnerabilities

Resolves 29 security issues identified by CodeQL scanning:

Security fixes:
- Log injection (27 instances): Sanitize user-provided values before logging
  to prevent attackers from injecting fake log entries via newline characters
- Unsafe quoting (1 instance): Use base64 encoding instead of embedding JSON
  directly in shell commands to prevent quote breakout
- JS log injection (1 instance): Sanitize event names in frontend logging
- Unused variable (1 instance): Remove unused setChatOpen setter

Implementation:
- Created logutil.SanitizeForLog() helper to remove newlines and control
  characters from user input before logging
- Applied sanitization across all backend handlers and orchestrator code
- Fixed unsafe shell command construction in openclaw.go by using base64
- Sanitized frontend console.log output in useChat.ts
- Prefixed unused variable with underscore in InstanceDetailPage.tsx

All fixes maintain existing functionality while eliminating security risks.
