Add Verse By Verse: Nuggets sub-show with editable hosts and RSS feed

New /nuggets page for the companion show, linked from the Episodes nav
dropdown. Hosts (name, role, bio, photo) show in a left column with the
episode list on the right — latest episode featured, rest below.
Episodes are pulled from an admin-configurable RSS feed URL (empty by
default, shows "coming soon" until set) rather than hardcoded like the
main show's feed, since the show doesn't have one yet.

Everything is editable in /admin under a new Nuggets section: Show
Settings (title, tagline, description, podcast art, RSS/platform URLs)
and Hosts (add freely; removing a host archives them instead of
deleting — kept on record and restorable, never lost).

Extracted the RSS item-parsing logic shared with the main show's feed
(server/routes/episodes.js) into server/rss-helpers.js so both feeds
use the same parser instead of duplicating it.

Also fixes the local Vite dev server not proxying /uploads/* to the
backend — it was silently serving the SPA shell (200, text/html)
instead of the actual file, so any admin-uploaded image (podcast art,
host photos, etc.) appeared broken in local dev only.
