Show full URLs in the source lists; SP indexer → tweaks.coinos.io

- Data-source and SP-indexer dropdowns now show the endpoint URL alongside the
  name (e.g. 'coinos — wss://electrum.coinos.io'), so it's clear where data comes
  from; 'Custom' stays bare.
- The tweak indexer is now served at https://tweaks.coinos.io (was halwallet.app/
  sp): a cloudflared route on the bitcoin tunnel → the indexer at :8888, with a
  DNS CNAME. Verified from a browser: /height, /mempool (1064 items), and /ws all
  work (the coinos.io Bot Fight Mode challenges non-browser clients only).
