fix(traffic): fix flow counter inflation from TOCTOU race in agent traffic reporter

Browse Source 
Replace read-then-subtract pattern in collectAndReport with atomic
swap-to-zero to eliminate race where AddTraffic increments counters
between snapshot and clearReportedTraffic, causing residual traffic
to accumulate indefinitely and inflate user flow counters.

Also add defensive check in processFlowItem to skip AddFlow when
forward no longer exists, and send DeleteService to clean up orphaned
agent services.
