feat: migrate from static config to database and add authentication

- Replaced static hosts.json and staticConfig.ts with SQLite database (Prisma)

- Implemented JWT authentication and Login UI

- Added dynamic API routes for hosts, topology, and settings

- Updated UI components to fetch and manage state dynamically

- Added Settings interface for managing hosts and topology nodes
