debug(timer): add comprehensive logging and fix config access

Add detailed console logging throughout timer decoration creation to
help diagnose rendering issues. Fix global configuration access by
properly setting timerConfig instead of undefined global variables.

- Add debug logs for each step of decoration creation process
- Log file processing, task detection, and decoration count
- Fix timerConfig initialization in taskTimerExtension function
- Add test file with proper frontmatter for timer functionality
- Enable troubleshooting of timer widget display issues
