fix(v2): move Dashboard to tool links + fix Combat sidebar button

- Dashboard toggle moved from sidebar header to tool links area
  alongside Suitbuilder, Inv Search, Debug, Quests
- Combat sidebar button now opens a character picker window
  (combatpicker prefix) that lists all online characters — click
  one to open their full combat stats window
