fix: activate discipline before adding XP in e2e test

- Disciplines section starts collapsed: click header to expand
- Raw Mana Mastery must be activated before XP can be added (handleAddXP bails if discipline not in store)
- Also needed because debugBridge changes require a fresh build (dev server was stale)
