logs latency in TS API (#3042)

<!-- CURSOR_SUMMARY -->
> [!NOTE]
> Add elapsed-time logging by timing requests and passing start time to
`httpLogger` across all response paths.
> 
> - **Runtime/Logging**:
> - Update `httpLogger` to accept `startMs` and log request latency in
ms.
> - Capture `start = Date.now()` in `apiHandler` and `createMainRouter`
request handlers.
> - Invoke `httpLogger(req, res, start)` on all exits (auth failures,
success responses, errors, 404) in
`packages/ts-moose-lib/src/consumption-apis/runner.ts`.
>
