Subject: refactor(client): migrate API calls to typed RPC client
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace raw fetch() calls with apiClient.rpc typed client across all
modal and page components. This provides better type safety and
eliminates manual auth header handling.

- Make handleResponse public for component usage
- Update all component tests to mock RPC methods instead of fetch
- Change POSTGRES_HOST default to kioku-db for Docker compatibility
