feat: unify search state and dynamic container routing

Refactor search handling across the frontend and backend to use a unified reactive state and dynamic container ID generation. The frontend now leverages a centralized `useMediaServers` composable for search queries and results, while the backend computes container IDs dynamically from source entries instead of using hardcoded values. Bumps version to 0.3.52.
