[POLISH] Docker setup fix + UI polish + project completion

- Fix Docker: add php.ini, correct env var names (DB_NAME/DB_USER/DB_PASS),
  add 002_email_log.sql to initdb, add Authorization header passthrough,
  add uploads volume, install opcache, create .dockerignore
- UI polish: page fade-in transitions, skeleton loader CSS, staggered card
  animations, mobile sidebar backdrop overlay, keyboard focus-visible styles,
  button loading state, tooltip system, alert banners, tab component,
  custom scrollbar, print styles, clickable table rows
- Add setButtonLoading() and _toggleSidebar() helpers to common.js
- Update CLAUDE.md to reflect 100% project completion
