📄 Description

Describe your changes

To reduce the frequency at which flow events are emitted, a client-aggregation of flow events is implemented in this PR.

Events are aggregated over a time window by destination address, destination port, protocol, and icmp code (for icmp). Total number of start-, end-, and drop-events is tracked, as well as the number of transmitted and received bytes and packets.

Summary by CodeRabbit

New Features
- Network flow events now include an aggregation window with start/end timestamps.
- Events now report per-flow counters for starts, ends, and drops.
- Flow event delivery is more reliable: events are aggregated and unacknowledged events are retried automatically until ACKed.
Documentation
- Updated API schema and generated models to include the new aggregation window fields and start/end/drop counters.
