Slim ark state for sync so it fits the relay's 64KB event cap

Cross-device ark sync silently failed: the full snapshot (deep-genesis
vtxo bytes + done-action signing hex) was ~153KB and relay.coinos.io
rejects events over 64KB, so no publish ever landed and other devices
never saw the balance. The synced ark state is now slimmed — spent
vtxos drop their signed bytes (kept only for spendable/pending, which a
device might spend/exit), done board/offboard/exit actions keep just
the fields history labels need (hex stripped), in-flight actions and
movements beyond the last 300 are dropped. Local storage keeps the full
state; only the published copy is slim. ~150KB -> well under 64KB.
