[mostronatorcoder]

Summary

Add a new /closecommunity command so superadmins can close a community by community ID or Telegram group handle.

Examples:

• /closecommunity 09f258490ac3d
• /closecommunity @GrupoComunidad

Requirements

• Command must be restricted to superadmins using validateSuperadmin.
• Accept either a community ID or the community group/username as input.
• After resolving the target community, send a confirmation wizard to the admin showing:
  • Community name
  • Completed orders
  • Creator: @Creador
  • Solvers: @Solver1, @Solver2, ...
• Confirmation text:

  Comunidad <nombre comunidad>
  Ordenes completadas:
  Creador: @Creador
  Solvers: @Solver1, @Solver2, etc..

• Include buttons:
  • Continuar
  • Cancelar
• If the admin presses Continuar, send a message to the community owner notifying them that an administrator closed their community, for example:
  • un administrador ha cerrado tu comunidad @NombreComm

Notes

• The command should perform the actual close flow only after explicit confirmation from the superadmin.
• The owner notification should only be sent after a successful confirmation and close action.
