test: expand coverage to 3,382 tests across all layers

- Unit: 1,353 tests (42 files) — +256 new tests covering AI bridge modules, image-engine sharpen/optimize-for-web, Zustand stores, and icon-map validation - Integration: 1,640 tests (57 files) — +826 new tests across all tool routes, pipeline/progress/batch infrastructure, user-files, edit-metadata, and a 321-test cross-format matrix - E2E-Docker: 389 passing (20 spec files) — 6 new spec files for batch processing, format conversion, layout, optimization, watermark/overlay, and pipeline chains. Tests verified against fresh Docker container with all 6 AI bundles installed. Bug fixes discovered during testing: - fix(compress): SVG/BMP/exotic formats crashed Sharp encoder — added format-safety fallback to PNG - fix(rate-limit): increase default login attempt limit from 10 to 500 per minute — previous value caused false test failures and is too restrictive for a self-hosted app - fix(auth.setup): wait for consent button visibility before clicking to prevent flaky E2E-Docker auth setup
