v2.3.67

What's Changed

• Enforce the core viewForum permission in group visibility — fixes group discussions/posts leaking to actors who lack viewForum on login-restricted forums (and the 401-while-content-shows inconsistency) (#5)
• Document why 5 migrations intentionally stay raw (audit #1 — not a defect)
