fix(profiles): scope switcher to supported app tabs and relocate it

- Render the profile switcher only when the active tab is Claude or
  Codex (frontend mirror of backend PROFILE_APPS), so viewing an
  unsupported app no longer suggests its config was switched
- Move the switcher from beside the logo to the right of the route
  toggles, where the flexible spacer absorbs its appearance and other
  header controls no longer shift when switching tabs
