feat: Add V2 of header actions slot (#682)

Introduce a v2 version of LearningHeaderActionsSlot that always mounts,
wrapping the existing v1 slot (HeaderNotificationsSlot and
LearningHelpSlot) which stays gated behind showUserDropdown. This
preserves the v1 slot API contract for existing plugin consumers while
allowing new plugins to attach to v2 unconditionally.

Note: HeaderNotificationsSlot/LearningHelpSlot remain hidden when
showUserDropdown is false. Fully decoupling them from showUserDropdown
requires deprecating v1 first, and is left for a
follow-up once the DEPR lands.
