fix(traffic): keep enforcing limits when one inbound's settings are broken

Disabling depleted clients rewrote each affected inbound's settings and
aborted the whole lifecycle tick when one blob did not parse, so a node
storing a malformed blob on the master switched expiry and quota checks
off for every inbound. Unparseable node settings are now treated like a
snapshot that drops the hub's clients (the hub keeps its copy), and an
unparseable stored blob is left as it is while the client's rows are
still disabled; the rewrite also works one level deep like the others.
