feat(docker-watcher): phase 14 - frontend polish & modern UI

Design system with CSS custom properties (light/dark themes).
38 Lucide SVG icon components. Dark mode with system preference.
EN/RU localization with i18n store. Skeleton loaders, empty states,
toggle switches, micro-interactions. Responsive sidebar with
mobile hamburger menu. All pages polished with consistent styling.

## Tasks
- [ ] Task 1: Design system foundations — define color palette (dark/light), spacing scale, typography scale, border radius tokens as CSS custom properties

## Acceptance Criteria
- UI looks modern and professional — not "default framework" appearance
- Consistent icon language throughout the app
- Smooth transitions and meaningful animations (not gratuitous)
- Responsive down to mobile viewport
- Loading and empty states provide good UX
- Color palette works well in both light and dark contexts
- All UI strings available in English and Russian, switchable via locale picker
## Notes
- This phase runs AFTER all functionality is complete — pure visual/UX enhancement
- Do not change any functionality or API contracts
- Prefer CSS custom properties for theming over hardcoded values
- Keep bundle size reasonable — inline SVGs preferred over icon font libraries
- Animations should be tasteful and serve UX, not decoration
- For i18n, use a lightweight approach (JSON locale files + Svelte store) — no heavy i18n framework needed
- Default language: English. Russian as secondary. Locale persisted to localStorage
