refactor: implement multi-tier logging and drop panicOnWarning

- Centralize logger: warnf/errorf for normal pages; HTML comments for adapters
- Add dev console logs and export structured logs to /hbx-debug.json
- Remove --panicOnWarning from dev scripts; builds no longer fail on warnings
- Fix prior lint/format issues across scripts and templates
