Build 50: production Nym requester; correct sender amount/fee; Nym copy

- Bake the always-on us-ea.st network requester into NETWORK_REQUESTER so a
  shipped wallet routes through the mixnet out of the box (override with
  GOBLIN_NYM_PROVIDER). Verified e2e: real wallet-to-wallet payment across two
  mainnet nodes (grincoin.org → main.gri.mw), recipient received the exact
  amount, all traffic over Nym.
- Fix the sender's displayed amount: a sent tx debits inputs and credits change,
  so debited-minus-credited is amount PLUS fee. Subtract the fee so the activity
  feed, receipt and history show the value that reached the recipient (0.01),
  not the fee-inclusive net (0.033). The receipt's "Network fee" now reads the
  real kernel fee instead of the change.
- Replace the remaining user-facing "Tor" copy with Nym (send/request review
  delivery line, connection status chips, onboarding, the Privacy settings row).

38 lib tests pass.
