Story Mode

## 1.8.5

### Classic Era
- Added **Poor Old Blanchy** as a Classic/TBC Alliance short story
- Expanded **Poor Old Blanchy** into a small Furlbrow family arc with **The Forgotten Heirloom** and optional **Furlbrow's Deed** context
- Added optional **Test of Lore** coverage to **The Scarlet Crusade**, with guidance that sends players to the **Test of Faith** chain starter first
- Updated Classic/TBC short-story cover art: **Poor Old Blanchy** now uses Ruined City, **Hogger** uses Dungeon, and **A New Plague** uses Scholomance

### UI
- Aligned Story Mode's private tooltip styling with Blizzard tooltip templates while keeping the taint-safe custom tooltip behavior
- Hardened Story Mode chat filters so non-Story Mode chat messages pass through with their original arguments untouched

### Maintenance
- Bumped addon metadata to `1.8.5`
