fix: Configure admin service URLs dynamically based on environment

- Update adminService to fetch server URL from /api/config endpoint
- Initialize server URL before making any API calls
- Make connect() method async to handle URL initialization
- Update Vue component to await adminService.connect()
- Resolves hardcoded localhost URLs in production environment
