privacy: only domain-anchored address resolvers; drop Cake endpoints

Address-field input no longer leaves the device except toward
infrastructure implied by the typed name itself:
- remove Twitter, Mastodon, Nostr, Yat, Unstoppable Domains, FIO,
  ThorChain-name, zcash.me, and Zano alias lookups (Nostr and FIO ran
  with no setting gate at all; Zano is not even a supported chain)
- keep OpenAlias, BIP-353, .well-known, LNURL, and ENS, each toggleable
  in Settings -> Domain lookups
- BTC fee/block/restore-height queries move from mempool.cakewallet.com
  to public mempool.space (also fixes two /api/v1 paths that 404 on
  standard mempool deployments)
- PRIVACY.md updated to disclose the remaining flows (mempool.space,
  name lookups, opt-in silent payments and payjoin); issue templates and
  the translation prompt de-Caked

 - **Price data.** The app fetches exchange rates from `prices.neroswap.com`, a
   service we operate that aggregates public sources. It sees your IP and the
   currencies you display — not your addresses or balances.
+- **Bitcoin fee and block data.** For Bitcoin wallets, the app queries the
+  public `mempool.space` API for recommended fee rates and block timestamps.
+  It sees your IP and the block heights queried — not your addresses or
+  transactions. This is on by default and can be turned off in settings.
+- **Name lookups.** If you type a human-readable name instead of an address,
+  the app can resolve it. Every resolver is limited to infrastructure implied
+  by the name itself, and each can be toggled in Settings → Domain lookups:
+  OpenAlias and BIP-353 query DNS; `.well-known` and Lightning-address
+  lookups contact the domain in the identifier you typed; ENS (`.eth` names)
+  queries the public Ethereum RPC at `ethereum-rpc.publicnode.com`. Hash Bags
+  does not send what you type to social networks or third-party identity
+  services.
+- **Silent Payments scanning (opt-in, Bitcoin).** If you enable Silent
+  Payments, scanning uses a compatible Electrum server (the current default,
+  `electrs.cakewallet.com`, is operated by Cake Labs, a third party). That
+  server sees your IP and the block ranges you scan — not your keys. You can
+  point it at your own server in settings.
+- **Payjoin (opt-in, Bitcoin, off by default).** If you enable Payjoin,
+  traffic is relayed through an oblivious-HTTP relay chosen from a small
+  public pool (currently operated by bobspacebkk.com, achow101.com, and
+  Cake Labs). The relay sees your IP but not the transaction contents.

   amount, receiving address) are sent to Trocador's API. Trocador is an
