PDF generation of CodiMD pages

Sometimes, CERN Indico users attach a link to their CodiMD document containing minutes. It would be nice to schedule a job (or after some time has passed) to automatically take the CodiMD document -> convert it into a PDF -> attach it to Indico.

There are a few pitfalls to this (with a few possible solutions):
* **When should we do this?** How and when should we determine when a meeting has ended and that all changes in the CodiMD are final? We could have a 48h delay after the meeting has officially ended (`end_dt + 48`) where we then execute the job to fetch the contents of the CodiMD (mockup attached below) - this could also be configurable (e.g. have an option to run the conversion immediately when the CodiMD link is saved or at a set period after the event finishes etc.).
* **How should we handle updates to the CodiMD document?** In other words: how should we handle the polling/refreshing of the CodiMD document? Should we even do this at all?

Mockup (rough):
