Add Finance channel (web-only) with markets/macro feeds

New web-only category mirroring the EU channel: shows in the web UI but
does not post to Matrix. Adds the channel entry, emerald (money green)
theme utilities, and two macro/finance feeds (Naked Capitalism, Wolf
Street) to the example config.
