perf(web): optimize frontend build with SWC and code splitting (#55)

* perf(web): optimize frontend build with SWC and code splitting

Replace Babel with SWC plugin (20x faster), add intelligent code splitting for vendor chunks, lazy-load heavy pages (swagger-ui, jspdf). Build time reduced from ~15s to ~10s, bundle size from 2.5MB to 761KB for initial load.
