refactor: Separate network communication from packet capture logic & …

[smitmartijn]

…introduce PF_RING captures

Move overarching service orchestration to main.cpp and create dedicated NetworkClient and CaptureService components for better separation of concerns.

New Architecture:

• main.cpp: Service orchestrator handling both capture and network clients
• NetworkClient: Manages TCP connection to WhatPulse with auto-reconnect
• CaptureService: Handles packet capture and interface monitoring only
• IPacketHandler: Interface for cleaner packet handling abstraction

Pull Request Overview

This PR refactors the PCap service architecture to separate network communication from packet capture logic and introduces PF_RING high-performance packet capture support.

• Refactors monolithic PcapService into specialized components (NetworkClient and CaptureService)
• Introduces PF_RING packet capture support with fallback to traditional PCap
• Creates cleaner interface abstractions with IPacketHandler for packet handling
