fix: strengthen Google Places name validation to prevent cross-company data contamination

- Replace substring matching with word-boundary tokenized matching
- Short names (1-2 words): require ALL significant words to match
- Longer names (3+): require at least 50% word overlap
- Pick best-scoring result instead of first match
- Add company_name validation to competitor_monitoring_service
- Show Google profile name in dashboard hints for admin verification
- Display mismatch warning when Google name differs from company name

Prevents cases like "IT Space" matching "Body Space" (score 0.50 < 1.00 threshold).
