feat(coordinator-api): add global exception handler and rate limiting to marketplace and exchange endpoints

- Add general exception handler to catch all unhandled exceptions with structured error responses
- Add structured logging to validation error handler with request context
- Implement slowapi rate limiting on marketplace endpoints (100/min list, 50/min stats, 30/min bid)
- Implement slowapi rate limiting on exchange payment creation (20/min)
- Add Request parameter to rate-limited endpoints for slow
