Goblin Build 135 - Tor credit, balance updating indicator, Nym sweep

- Third-party credits: replace the "Nym mixnet" row with "Tor (arti)" (0.43,
  linking the arti repo), matching the other credit rows' hardcoded style. No
  locale strings existed for it (credit labels are hardcoded, not localized).
- Balance: show a quiet "Updating…" line under the balance while the node is
  still warming, reusing the existing wallet.syncing() signal and the
  balance-updating line's muted style; it clears once the node is synced. New
  t!() key goblin.home.updating added to all six locales (i18n drift green).
- Nym sweep: Cargo.toml package description "Nym mixnet" -> "Tor". The only
  other user-facing Nym reference was the credit above. Remaining references
  are the deliberately-dormant `nym` feature/module and internal code comments,
  left as-is; README and all locale values were already Tor.
