Keep last good feed snapshot on failed polls (!15)

- Poll failures write =ll2:error= / =swpc:error= rows instead of overwriting the feed's row.
- Before: a failed LL2 poll (HTTP 429 from Cloudflare's shared egress IPs) set =ok = 0= on =ll2=, so =/v1/launches= returned =fetchedAt: null= while still serving 20 launches; a failed SWPC poll would have hidden space weather entirely.

=node --test=: 10 pass. Deployed after merge.
