feat(load-tests): add K6 load testing suite for critical API paths

K6 scripts for 4 critical paths: - Auth (100 VU): login, register, profile - Listings (500 VU): search with filters, detail view - Search (200 VU): full-text + geo search - Payments (50 VU): create payment, list transactions SLA thresholds: p50<200ms, p95<500ms, p99<1s, error<1%. CI: manual workflow_dispatch with suite selector. Co-Authored-By: Paperclip <noreply@paperclip.ing>
