Fix regex pattern for page detection

Changed from:
  /^(\d+)\s+pages?$/i  (exact match only)
To:
  /(\d+)\s+pages?/i    (matches anywhere in text)

Added:
- Shows ALL text matches found
- Logs which div contains the match
- Searches in body text as fallback
- Better visibility into what text exists

This will reveal why page detection is failing!
