Fix realm-gate disable for book/options, pet-rank learning, unique beasts

- Hunter's Book and options window now show a full 'DISABLED.' overlay on realm-gated realms instead of rendering content
- Pet training: new rank of an already-known ability is now recognised, announced, and reflected in tooltips
- Restore curated 'unique appearance' beast allowlist (34 beasts) in data/init.lua
- CHANGELOG updated
