Caching images in blog posts

[Cwpute]

• Cache blog post API query
• Save blog post images in the minio instance

This issue follows exchanges on the Discord (https://discord.com/channels/1070731899317796974/1284146860130439281):

Was reading psi's zapatista short comic, and as i was trying stuff out, poking at different stuff on Mirlo's website, i kept reloading and reloading the same blog post. And after several refresh, i noticed my data consumption rising and rising...! I suspect it was the post's embedded image that kept being downloaded again and again !
Could this be the case ? Is there a limit to the size of pictures displayed on any blog post ? does Mirlo resizes pictures uploaded by users so they don't feature any absurd size and gobble up ye poor man's data ?

The images in blog posts need a lot of improvement
The easiest win is probably caching the blog post api query
I don’t think that gets done atm
The bigger lift is that I think we actually need to save blog post images in our minio instance
