fix: cron panel crash on missing schedule + doctor parser false positive (#347)

- Filter out cron jobs with missing/empty schedule before processing,
  preventing TypeError on .toLowerCase() (#342)
- Add defensive .localeCompare() guard in sort comparator
- Exclude positive/instructional lines ("No ... warnings detected",
  "Run: ...") from doctor issue extraction (#331)
- Strip negated warning phrases before keyword detection so "No channel
  security warnings detected" doesn't trigger warning level
- Add 2 tests for the doctor parser fix
