Generate static params

[exacs]

This PR implements generateStaticParams for the nextjs-template

[Copilot]

Pull request overview

This PR adds static site generation (SSG) support to the Next.js template by implementing the generateStaticParams function. This function queries all pages from Optimizely CMS at build time and generates static routes for them, improving performance by pre-rendering pages. The implementation includes adding a new APPLICATION_HOST environment variable to filter pages belonging to the current application.

Key Changes

• Implements generateStaticParams to fetch and generate static routes for up to 100 pages from Optimizely CMS
• Adds dynamicParams = true configuration to allow non-pre-rendered routes to be handled at runtime
• Introduces APPLICATION_HOST environment variable for filtering pages by host
