Frontend (`ChannelsTable.js`)
1. Initialize `loading` state to `true` so the spinner is visible while the first data request is in-flight.
2. Set `<Table>` prop `loading={loading || searching}` — the spinner now appears for both the initial load and any subsequent search requests.

Result
Users immediately see a loading indicator on page entry and whenever a search is running, improving perceived responsiveness.
