feat(matches): implement spam protection and socket notifications

S15.1-15.2: Rate Limiting & Spam Protection
- Add max 20 pending outgoing match requests limit
- Implement rate limiter: 10 match requests per minute per user
- Return 429 status with clear error messages

S16.1: Socket Notifications for New Suggestions
- Emit 'recording_suggestions_created' event when matching creates suggestions
- Notify only assigned recorders (not NOT_FOUND status)
- Group suggestions by recorder for efficiency
- Include event details and suggestion count

Implementation:
- backend/src/routes/matches.js: Rate limiter + pending limit check
- backend/src/services/matching.js: Socket notifications in saveMatchingResults
- backend/src/__tests__/spam-protection-notifications.test.js: 8 test cases

Test coverage:
- TC1-TC3: Max pending requests (spam protection)
- TC4-TC5: Rate limiting (10/min)
- TC6-TC8: Socket notifications for new suggestions
