Improve NanoKVM Pro support and device compatibility handling

[chiconws]

Summary

This PR expands NanoKVM Pro support and tightens device compatibility handling across the client.

What changed

• added missing NanoKVM Pro client methods for:
  • scripts
  • HID shortcuts and leader key
  • Wake-on-LAN MAC management
  • AP-mode Wi-Fi helpers
  • custom EDID upload/delete
  • LCD time format
  • LED strip
  • timezone and time sync
  • menu bar config
  • static IP
  • stream configuration
  • Tailscale login URL
  • PiKVM switch
  • kvmadmin and assistant endpoints
• unified virtual device parsing so shared client code works with both legacy and Pro response shapes
• improved Pro model coverage with richer types for:
  • EDID presets
  • LCD time format
  • stream mode
  • OLED type
• normalized compatibility edge cases for Pro payloads:
  • nullable files
  • nullable wifiList
  • nullable edidList
  • nested Wi-Fi details
  • optional pn / arch
• preserved partial LED strip updates by filling missing values from current device state
• fixed password change behavior so it respects the detected password mode
• improved shared API error handling so undocumented device error codes are surfaced correctly
• normalized the empty Wake-on-LAN file state to an empty list
• mapped legacy swap 404 responses to NanoKVMNotSupportedError

Notes

• the branch keeps the current explicit hardware-detection requirement for hardware-gated methods
• image download route selection remains aligned with the current dev behavior
• the changes are focused on client behavior and compatibility, without broad refactoring of the existing architecture
