Fix 500 error tracker diagnostic output bugs

Browse Source 
Fixed three issues in the diagnostic output display:

1. Integer expression error: Changed from grep -c to wc -l with sanitization
   to prevent "integer expression expected" errors from newlines

2. ANSI escape codes: Added -e flag to echo statement so color codes
   render properly instead of showing as raw \033[2m sequences

3. Duplicate domains: Implemented two-pass deduplication system using
   sort -u to show unique domains per issue pattern, preventing repetitive
   output like showing the same domain 5 times
