fix(doctor): wire up CheckRedirectNotTracked and FixRedirectTracking

Completes the work from #813 by actually calling the new functions:
- Add Check 14b in doctor.go for redirect file tracking detection
- Add Redirect Not Tracked case in doctor_fix.go switch statement

Without this wiring, bd doctor would not detect or fix already-tracked
redirect files, only prevent new ones via the updated .gitignore template.
