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
