Accepting the one-time login restore offer used to pull the encrypted copy once
but never set the per-device sync flag — so users "restored once and stopped
syncing", and the settings toggle showed OFF despite having just restored. That
is exactly the "not syncing / has to keep confirming" behavior we're removing.
Accepting now means "keep this device in sync": after a successful pull we call
setSyncEnabled(pubkey, kind, true), so future saves auto-push (conflict-checked)
with no further prompts. Declining still enables nothing. No immediate push is
needed — we just pulled, so local == remote.
This completes the seamless model: enable once (or accept the offer once) →
saves auto-push on conflict-only confirm, restores pull with a small toast.
Tests: settings-restore-prompt.test.mjs +2 — accept enables the restored item
(and only that item); decline enables nothing.
