feat: private balance

[Dodecahedr0x]

Authenticate to the PER when getting private balances

Summary by CodeRabbit

• New Features

  • Wallet message signing is now required to authenticate and view private SPL balances; UI shows an “Authenticate” overlay when connected but unauthenticated and detects wallets without signing support.
  • Net worth panel displays dynamic per-token balances (replaces hardcoded rows) with per-token loading (“…”) and missing-data (“—”) states.
  • Auth tokens are persisted per wallet; balances refresh after payments and via a global refresh event.

• Bug Fixes

  • Token is cleared and re-authentication prompted on balance-load or auth failures.

Walkthrough

Replaced wallet-modal connect with wallet message-signature authentication for private SPL balances; added client helpers for challenge/login/balance fetch and storage, an event-based refresh helper, a payment-card refresh trigger, and added bs58 dependency.

Changes

Cohort / File(s)	Summary
NetWorth Panel components/one/net-worth-panel.tsx	Replaced wallet-modal connect flow with SPL message-signature auth: load/store per-owner auth token, fetch+sign challenge and login to obtain token, persist/clear token on owner change/errors, fetch private balances in parallel for configured mints, show loading (…) / missing (—) states, handle balanceError, and listen for PRIVATE_BALANCE_REFRESH_EVENT.
SPL Private Balance Library lib/spl-private-balance.ts	New module: get/set/clear localStorage helpers for per-pubkey auth tokens, fetchSplChallenge, loginSplPrivate, fetchPrivateBalance (Bearer auth + cluster), formatBaseUnits, and PrivateBalanceRow type with robust error handling and safe window checks.
Private Balance Refresh lib/private-balance-refresh.ts	New module exporting PRIVATE_BALANCE_REFRESH_EVENT and dispatchPrivateBalanceRefresh() which dispatches a browser CustomEvent (no-op on server) to prompt refetch.
Payment Card components/one/payment-card.tsx	Invoke dispatchPrivateBalanceRefresh() immediately after a payment transitions to "confirmed" to trigger private-balance listeners to refresh.
Dependencies / Manifest package.json	Added dependency bs58 (^6.0.0).
