The sibling-rotation path's "Embedded PPSK not found" error was being
surfaced to the operator as a failure, but it's not — it just means
the PPSK isn't mirrored on that band (GUEST was configured on one
band only, which is a perfectly valid setup). Logging this as a
sibling failure also poisoned the cron run status to "partial".
Now: "not found"-style errors from updateEmbeddedPpsk on a sibling
become info-level log entries and the loop continues. Other errors
(API failures, permissions, etc.) still surface as warnings/failures.
