fix(ui): classify ended clients as depleted, not disabled, on inbounds page

The auto-disable job flips client.enable off in the settings JSON when a
client expires or exhausts its traffic, so the inbounds-page rollup filed
every ended client under the gray Disabled badge (and double-counted it
in Depleted when stats were present). Classify with depleted-first
priority, matching computeClientsSummary and the client info modal.

Also backfill cross-inbound client_traffics rows in GetInboundsSlim:
the row is keyed on email and only preloads on the inbound the client
was created on, so on every other attached inbound the depleted/expiring
checks could never fire.
