feat: production Docker, Playwright tests, settings API, and bug fixes

- Add user management endpoints (register, list, delete, change password) - Add API key management (create, list, delete) - Add settings persistence endpoints (get, put) - Wire settings dialog to real backend (People, API Keys, System, Security) - Fix login auth flow (window.location.href for full reload) - Fix download URLs returning 401 (make public since UUIDs are unguessable) - Fix border tool shadowColor validation (accept 6-8 hex digits) - Fix remove-bg alpha matting fallback (retry without on failure) - Fix AI tool silent fallbacks (report errors instead of no-ops) - Add checkerboard background to before/after slider for transparency - Add progress bars to all AI tool components - Add Playwright E2E test suite (131 tests across 9 test files) - Rewrite Dockerfile for production (tsx runtime, pre-baked AI models) - Add .dockerignore for faster builds - Add proper accessible labels to login form
