fix(openclaw): address code review findings for robustness

- Fix EnvPanel visibleKeys using entry key name instead of array index
  to prevent visibility state corruption after deletion
- Add NaN guard in AgentsDefaultsPanel numeric field parsing
- Validate provider id and models before importing from live config
- Upgrade import failure log level from debug to warn for OpenCode/OpenClaw
