config(dev): adjust API connection timeout (#5754)

## Problem

- The API connection was timing out after 120 seconds, leading to a poor
customer experience (CX). Users were waiting for 2 minutes before
receiving a timeout error, which is an unacceptably long wait time.

## Solution

- Adjust the API connection timeout to 10 seconds, which is
approximately 3 times the high band of the API's P99 latency.
- This change should improve the user experience by failing fast in case
of connection issues.
