fix: use explicit initializeBase key for query invalidation

Mutations were invalidating with initialize() which produces a key
with trailing undefined, relying on React Query implementation details
for prefix matching. Added initializeBase() that produces a clean
prefix key ['learner-dashboard', 'initialize'] for unambiguous
invalidation of all initialize queries regardless of masquerade user.
