fix: FAQ CJK glyphs, outgoing-tx history, lite encryption, migrate & sync safety

Bug-report fixes plus adversarial-audit follow-ups. Bumps full 2.0.1->2.0.2 and
lite 1.1.0->1.1.1.

i18n / fonts:
- Rebuild the NotoSansCJK subset with the glyphs the FAQ back-fill introduced
  (什/么/门/做); Chinese FAQ titles rendered as "??" on zh (and ja/ko).

Transaction history (enumeration gaps):
- Surface outgoing shielded z->z sends via z_listsentbyaddress (listtransactions
  and z_listreceivedbyaddress never report them).
- Surface z->t deshields by parsing z_listsentbyaddress transparentSends (which
  z_viewtransaction does not expose); dedupe t->t against listtransactions.
- Key send-row dedup on address so equal-value multi-output sends aren't dropped.

Lite wallet (key safety):
- The async create/restore/open path the UI uses now applies the passphrase:
  encrypt a new/restored wallet, unlock an existing one. It previously discarded
  the passphrase, storing the seed/keys in PLAINTEXT (create/restore) or leaving
  an encrypted wallet locked (open).

Migrate-to-seed (fund safety):
- Persist a sweep-submitted marker at broadcast so a resumed migration can't treat
  a ~0 balance (an unconfirmed in-flight sweep) as an empty wallet and adopt (swap
  wallet.dat) before the sweep confirms; best-effort locate routes to the confirm gate.

Sync / threading:
- Gate isSynced() on a peer-derived tip (tip_known) so a peerless node isn't reported
  synced (Send against a stale balance); add a "no peers" status banner.
- Guard daemon_status_ with a mutex (monitor-thread write vs UI-thread read).

Tests: extends tests/test_phase4.cpp across all of the above; suite green.
