973bacf783 docs: Data API IA (#42417)
*Summary*
- reorganize the navigation menu to highlight modules, consolidate API
security content, and move guide entries (auto-generated docs, type
generation, security topics) to the intended sections
- relocate the Data API hardening and custom claims RBAC guides into the
API subtree, updating internal references and redirects, and fixing
cross-links (including adjusting the Security reference order)
- adjust data API topic references (e.g., securing guide and role
management) to point to the new paths and ensure the helper link
ordering follows the requested layout

*Testing*
- Not run (not requested)

Supabase auto-generates an API directly from your database schema allowing you to connect to your database through a restful interface, directly from the browser.
The API is auto-generated from your database and is designed to get you building as fast as possible, without writing a single line of code.
You can use them directly from the browser (two-tier architecture), or as a complement to your own API server (three-tier architecture).
## Features [#rest-api-overview]
Supabase provides a RESTful API using [PostgREST](https://postgrest.org/). This is a very thin API layer on top of Postgres.
It exposes everything you need from a CRUD API at the URL `https://<project_ref>.supabase.co/rest/v1/`.
The REST interface is automatically reflected from your database's schema and is:
- **Instant and auto-generated.** <br />As you update your database the changes are immediately accessible through your API.
- **Self documenting.** <br />Supabase generates documentation in the Dashboard which updates as you make database changes.
- **Secure.** <br />The API is configured to work with PostgreSQL's Row Level Security, provisioned behind an API gateway with key-auth enabled.
- **Fast.** <br />Our benchmarks for basic reads are more than 300% faster than Firebase. The API is a very thin layer on top of Postgres, which does most of the heavy lifting.
- **Scalable.** <br />The API can serve thousands of simultaneous requests, and works well for Serverless workloads.
The reflected API is designed to retain as much of Postgres' capability as possible including:
- Basic CRUD operations (Create/Read/Update/Delete)
- Arbitrarily deep relationships among tables/views, functions that return table types can also nest related tables/views.
- Works with Postgres Views, Materialized Views and Foreign Tables
- Works with Postgres Functions
- User defined computed columns and computed relationships
- The Postgres security model - including Row Level Security, Roles, and Grants.
The REST API resolves all requests to a single SQL statement leading to fast response times and high throughput.
