Keep every enclosure on an item, and view without downloading

The rss crate keeps at most one enclosure per item and, when a feed ships
several, silently keeps the last -- so a two-file item lost its first
file. enclosures_by_item reads them from the XML in document order,
unescaping attributes so a URL's & survives. The row summarises the
one you would act on and counts the rest; the pane below lists them all.

Non-media enclosures gain a View link opening in a new tab: the
publisher's URL, or the local copy once downloaded. A direct link, not a
proxy, so the daemon does not become a fetch-anything relay.
