Add Fritz!Box device scanner plugin via TR-064 protocol

NetAlertX had no native support for discovering devices connected to
Fritz!Box routers. Users relying on Fritz!Box as their primary home
router had to use generic network scanning (ARP/ICMP), missing
Fritz!Box-specific details like interface type (WiFi/LAN) and
connection status per device.

Changes:
- Add plugin implementation (front/plugins/fritzbox/fritzbox.py)
  Queries all hosts via FritzHosts TR-064 service, normalizes MACs,
  maps interface types (802.11→WiFi, Ethernet→LAN), and writes results
  to CurrentScan via Plugin_Objects. Supports filtering to active-only
  devices and optional guest WiFi monitoring via a synthetic AP device
  with a deterministic locally-administered MAC (02:xx derived from
  Fritz!Box MAC via MD5).

- Add plugin configuration (front/plugins/fritzbox/config.json)
  Defines plugin_type "device_scanner" with settings for host, port,
  credentials, guest WiFi reporting, and active-only filtering.
  Maps scan columns to CurrentScan fields (scanMac, scanLastIP, scanName,
  scanType). Default schedule: every 5 minutes.

- Add plugin documentation (front/plugins/fritzbox/README.md)
  Covers TR-064 protocol basics, quick setup guide, all settings with
  defaults, troubleshooting for common issues (connection refused, auth
  failures, no devices found), and technical details.

- Add fritzconnection>=1.15.1 dependency (requirements.txt)
  Required Python library for TR-064 communication with Fritz!Box.

- Add test suite (test/plugins/test_fritzbox.py:1-298)
  298 lines covering get_connected_devices (active filtering, MAC
  normalization, interface mapping, error resilience), check_guest_wifi_status
  (service detection, SSID-based guest detection, fallback behavior), and
  create_guest_wifi_device (deterministic MAC generation, locally-administered
  bit, fallback MAC, regression anchor with precomputed hash).

Users can now scan Fritz!Box-connected devices natively, seeing per-device
connection status and interface type directly in NetAlertX. Guest WiFi
monitoring provides visibility into guest network state. The plugin
defaults to HTTPS on port 49443 with active-only filtering enabled.
