Data-loss bug: on a fresh device the user opened the Wallet pane (field empty,
wallet not yet restored), clicked Save, and the "removed" branch called
walletSync.disable() — publishing a {cleared:true} note that destroyed the good
encrypted copy another device relied on. (Confirmed in logs: a kind-30078
"bitvid:nwc" {cleared:true} event signed right after login.)
An empty save happens routinely (saving before hydration/restore), so treating it
as a deliberate disconnect-that-wipes-the-remote is wrong. Removed the auto-clear
from the empty-save branch: the remote synced note is now changed ONLY via the
explicit sync toggle (enable/disable) or a successful save (push). An empty save
clears just the LOCAL wallet.
tests/wallet-sync-no-clobber.test.mjs: empty save does not call disable/push; a
real save still pushes. Mutation-verified (re-adding the disable fails the test).
