gameplay: fix talent reset and ignore list population on login

- SMSG_IGNORE_LIST was silently consumed; now parses guid+name pairs to
  populate ignoreCache so /unignore works correctly for pre-existing
  ignores loaded at login.

- MSG_TALENT_WIPE_CONFIRM was discarded without responding; now parses
  the NPC GUID and cost, shows a confirm dialog, and sends the required
  response packet when the player confirms. Without this, talent reset
  via Talent Master NPC was completely broken.
