Fix console_ui.py: module-level NameErrors from deferred imports, restore_arp_ui crash

[Copilot]

console_ui.py defined functions before their dependencies were imported, causing NameError at module level (line 725, in <module>). Additionally, restore_arp_ui passed stdscr.getmaxyx (a method object) as IP string arguments to restore_arp(), crashing on every invocation.

Changes

• Restructured import order — all imports (curses, netifaces, arp_spoof, proxy_server, etc.) moved to the top of the file; logo_art constant and all function definitions follow in a clean, linear order
• Removed broken import retry loop — eliminated the while True: try/except: block with bare except that could spin forever if dependencies never resolved
• Fixed restore_arp_ui — replaced the incorrect call:

  # Before (crashes: passes method object, not IP strings)
  restore_arp(stdscr.getmaxyx, stdscr.getmaxyx)
  
  # After: scan network → user selects target → detect gateway → restore
  restore_arp(target_ip, gateway_ip)

  UI now scans the network, lets the user pick target devices, resolves the gateway per target, and calls restore_arp with correct IP string arguments, reporting per-host success/failure.
