feat: add GetActionBarPage and ChangeActionBarPage for bar switching

Browse source 
GetActionBarPage() returns the current action bar page (1-6).
ChangeActionBarPage(page) switches pages and fires ACTIONBAR_PAGE_CHANGED
via the Lua frame event system. Used by action bar addons and the
default UI's page arrows / shift+number keybinds.

Action bar page state tracked in Lua global __WoweeActionBarPage.
