SyncStatus

Observable state of wallet syncing, exposed by MidnightWallet.syncStatus.

Covers EVERY heavy sync the wallet runs — dust replay, shielded-balance refresh, and the genesis rebuild — not just dust. Syncing.phase names which one (a SyncPhase state, NOT display text) so a single observer (the foreground-service Live-Update notification, or any UI not driving the sync itself) can reflect whichever phase is in flight; the presentation layer maps the phase to a localized label.

Until #235 progress was only a per-call syncDust(onProgress) lambda — fine for the in-app WalletSyncIndicator, but a background observer needs an observable source. This is that source.

The eventsProcessed == -1 sentinel from the dust replay maps to Syncing(fraction = null, phase = Finalizing) — the "replaying" tail where a determinate percentage isn't available.
