Add a browser-facing Miniflux URL and link feeds to their entries page

The pipeline talks to Miniflux on loopback, so links meant for a person
need their own base. `[miniflux].public_url` defaults to base_url, and
`feed_url` builds the web UI's `/feed/{id}/entries` page, which the feeds
dashboard now uses instead of the non-existent `/feeds/{id}` route.
