Make silent-payment receives first-class in the UI

- One Receive card with an Address ⇄ Silent payment toggle (no separate card, no
  BIP-352 badge, no scan-status line or Rescan button — discovery is automatic).
- SP receipts appear in History like normal payments: wallet.history merges BIP84
  txs with per-tx SP receive rows (spTxRows), newest first; the detail view and
  pagination use it. SP outputs carry a firstSeen timestamp.
- Receive description simplified to 'A reusable address that can't be tracked.'
- Removed the '· Silent payment' tag from the Send recipient line.

Verified on regtest: a received SP shows in history and balance with no manual
scan.
