Scholomance: Real-ESRGAN-upscaled Atlas classic map + hand-pinned bosses

Real path forward for Scholomance after exhausting the upreza ecosystem (no classic-layout dungeon interior maps exist there because vanilla/TBC clients didn't ship dungeon interior maps — confirmed from WoWMapUprezClassic README + WoWMapUprezTBC contents).

Solution:
- Atlas-addon Scholomance.blp (512x512, classic single-room layout) upscaled to 2048x2048 with Real-ESRGAN x4plus. Numbers 1-14 are crisp and readable.
- New 'bosses' field in dungeon_replacements lets us hand-pin every enemy to a specific (x,y) on the new map. 14 classic Scholo bosses placed on their Atlas-numbered rooms.
- Single-floor dungeon (kg's 4-floor split is bypassed entirely).
