Add Docker stack, frontend redesign, and visual page inspector fix

Browse source 
- Redesigned frontend with Outfit/Figtree typography, coral accent palette,
  noise texture, glassmorphism header, and staggered animations
- Split monolithic index.html into modular JS (app, api, upload, batch,
  results, page-viewer, utils) and extracted CSS
- Fixed worker.py to generate page images for Visual Page Inspector
- Added Docker Compose stack (web, worker, redis, postgres)
- Added batch upload, HTML report export, rate limiting, and Redis queue
- Extended test suite with checker, remediation, worker, and DB tests
