feat: Keep-Alive correlation, TTL management, SIGHUP handling, logrotate support

Major features:
- One-to-many correlation mode (Keep-Alive) for HTTP connections
- Dynamic TTL for network events with reset on each correlation
- Separate configurable buffer sizes for HTTP and network events
- SIGHUP signal handling for log rotation without service restart
- FileSink.Reopen() method for log file rotation
- logrotate configuration included in RPM
- ExecReload added to systemd service

Configuration changes:
- New YAML structure with nested sections (time_window, orphan_policy, matching, buffers, ttl)
- Backward compatibility maintained for deprecated fields

Packaging:
- RPM version 1.1.0 with logrotate config
- Updated spec file and changelog
- All distributions: el8, el9, el10

Tests:
- New tests for Keep-Alive mode and TTL reset
- Updated mocks with Reopen() interface method
