fix: address Prajwal's review feedback on tutorial

- Add Overview section at top of tutorial
- Add anchor links in Prerequisites to Couchbase Cluster Setup and
  ToolJet Setup sections
- Add Couchbase docs links for loading travel-sample and allowing IPs
  in Capella
- Clarify self-managed Data API endpoint is server hostname/IP, not
  always localhost
- Add ToolJet self-hosted setup docs link
- Remove redundant connection details table in Step 2, replace with prose
- Remove duplicate Capella/Self-Managed sub-sections inside Step 2
- Move FTS index creation into Prerequisites section with cross-reference
  in Step 9

+## Overview

 In this tutorial, you will build an **Airline Dashboard** — a fully functional internal tool that lets you browse, search, create, edit, and delete airline records stored in Couchbase. You'll use ToolJet's visual app builder and connect it to Couchbase using the Couchbase marketplace plugin, covering all 6 supported operations.
 
 By the end, you'll have a deployed web app that your team can use immediately — no backend code, no frontend framework, no deployment pipeline required.
