Clicking 'Back up now' on the Lightning seed banner only navigated to
the LND app page — and the backup card there hid itself permanently if
its single status fetch failed (common right after a fresh install),
so the click appeared to do nothing.
The banner now deep-links with ?seed-backup=1, which the LND page uses
to open the reveal flow directly, and the card retries its status fetch
with backoff instead of giving up after one failed RPC.
