fix(clients): re-enable only quota-disabled clients on a traffic reset

Every traffic reset re-enabled its clients unconditionally, in the
client record and in the traffic row a master treats as the client's
state. A master forwards an inbound's scheduled reset and "reset all"
to its nodes through the per-client reset calls, so a client disabled
by hand on a node inbound came back on at the next scheduled reset.

Each reset now decides, before it zeroes the counters, which of its
clients the quota switched off, counting cross-panel usage, and
re-enables only those; a client disabled below its quota keeps its
record and traffic row off. The reset API docs say so.
