fix: review GATE A — reemplazo de contrasenas sin 3er operando y ANSI 5.1-compat

- wordpress/deploy.ps1: -replace no acepta tercer operando (count) en
  ninguna version de PS; bucle linea a linea (1a = root, 2a = MYSQL_PASSWORD)
- los 4 deploy.ps1: escape ANSI con [char]27 en vez de backtick-e
  (incompatible con Windows PowerShell 5.1); guard solo con NO_COLOR
