reader/processor: minimize the feed's entries html 

Compress the html of feed entries before storing it. This should reduce the
size of the database a bit, but more importantly, reduce the amount of data
sent to clients

minify being [stupidly fast](https://github.com/tdewolff/minify/?tab=readme-ov-file#performance), the performance impact should be in the noise level.
