Add DECK Frontend - Vite + TypeScript migration

- Migrated vanilla JS frontend to Vite + TypeScript
- Modular architecture: views, components, utils, api, state
- Three-panel layout: libraries (left), content (center), detail (right)
- Group name resolution via hstTags (set_hst -> readable name)
- Name priority: name_es -> alias -> ref -> hash truncated
- D3.js lazy loading in GraphView
- Hash-based routing
- Deployed to tzzrdeck.me
