feat(api): add dynamic server URL configuration to OpenAPI schema

Add a new postprocessing hook 'add_api_servers' that dynamically configures
the servers array in the OpenAPI specification based on the request environment.

This hook:
- Detects the current environment (local, staging, or production) from the
  request host
- Adds the current server URL as the primary option
- Includes production (https://api.prowler.com) as a fallback option when
  generating from non-production environments
- Enables users to toggle between local and production servers in Mintlify's
  API playground via a dropdown

Server detection logic:
- localhost/127.0.0.1 → "Local Development Server"
- hosts with 'dev' or 'staging' → "Development/Staging API"
- api.prowler.com → "Prowler Cloud API"

This enables the "Try it out" feature in Mintlify documentation and allows
testing against different environments without modifying the spec.
