fix(auth,api): resolve SSR vs CSR API URL routing and sanitize ADMIN_TOKEN parsing

- Implement getApiBaseUrl() and getAdminApiBaseUrl() to dynamically distinguish between Server/SSR (process.env.API_BASE_URL) and Client/CSR (process.env.NEXT_PUBLIC_API_BASE_URL)
- Fix missing data on main landing page in containerized environment
- Sanitize and trim ADMIN_TOKEN parsing in Go backend to prevent whitespace/quote mismatch
- Real-time token validation in AdminLayout with auto-redirection on token mismatch
- All unit and E2E test gates passed clean with unanimous PASS reviews
