The pushed frame serialized the delivery wall-clock time instead of the
post's own stored timestamp, and left the flag byte's low 2 attempt bits
always zero. Firmware sends the stored post timestamp and ORs in a fresh
random attempt so a retried post produces a different packet hash and
ACK; with a fixed timestamp two retries within the same second would be
byte-identical and dropped as mesh duplicates. The serialized timestamp
now also equals the push_post_timestamp sync watermark, matching the
firmware invariant.
