reduce number of contentful api calls

[parasquid]

right now we are not using as much api calls since the number of models in contentful is low.

what we can do is export the content via https://www.contentful.com/developers/docs/tutorials/cli/import-and-export/ then use that json to setup a small api mirror which the nextjs build system can then query.

this likely makes the website build a multi step process (export, run server, build) but theoretically it should prevent most of the api calls required to build the site

alternatively we can migrate over to https://payloadcms.com/docs/getting-started/installation and self host the headless cms ourselves

mentioning @ehvana here so you're aware :P

apparently payloadcms can be added into an existing app: https://payloadcms.com/docs/getting-started/installation#adding-to-an-existing-app

that means the cms together with the actual blog can be the same application. probably not something we want to do (since we are exporting to static html anyway) but something to consider if we ever need to build a site for a client that requires some cms capabilities.
