Jordan Ritter 5c7c82db46 fix(showcase/harness): correct resource_snapshots migration retention + null docs
Normalize the migration schema comments to reality: the heartbeat is 45s (not
the stale "~30-60s"), retention prunes by stable row id (robust to
same-millisecond observed_at ties) rather than a bare timestamp cutoff, and
document the null-vs-unavailable convention — the nullable number fields store
`null` for the `-1` "unavailable" sentinel so post-wedge queries cleanly
separate a measured reading from an unavailable one.
