feat: add multiple package sync sources and API integration

- Added undici dependency and implemented three package fetcher variants (simple text parsing, v2 with better error handling, and official repository sync)
- Integrated real API calls in PlatformSelector and PackageBrowser components with fallback to mock data
- Extended sync API route to support multiple data sources (debian-simple, ubuntu-simple, debian-official-v2, etc.) with platform initialization
