Feat/detect hotspot capabiliteis

[AghastyGD]

Summary

This PR adds hotspot capability detection based on the actual capabilities reported by NetworkManager.

Previously, wiretray assumed that any Wi-Fi adapter could be used for hotspot creation. In reality, not all wireless adapters support Access Point (AP) mode, which could lead to incorrect capability reporting and failed hotspot creation attempts.

What's included

Access Point capability detection

• Added support for reading WirelessCapabilities from NetworkManager.
• Detects whether a Wi-Fi adapter supports Access Point (AP) mode.
• Introduced DeviceCapabilities to model adapter capabilities.
• Added Device::supports_hotspot() helper.

Improved hotspot capability validation

• Hotspot support is now determined using actual adapter capabilities instead of simply checking for the presence of Wi-Fi devices.
• Candidate devices are filtered to include only adapters that support hotspot creation.

Device information in Settings

• Added a new Device Information page to the settings window.

• Displays:

  • Network interface name
  • Hotspot support status

This provides users with visibility into whether their hardware is capable of creating hotspots.

Why

Different Wi-Fi adapters expose different capabilities.

By detecting AP support directly from NetworkManager, wiretray can provide more accurate validation, better user feedback, and a stronger foundation for future hotspot configuration features.
