Scholomance: revert to single-floor Atlas map

The 4-floor upreza experiment placed bosses on Cata-redesign rooms which don't match Ascension's classic boss spawns. Going back to commit 58b3f74's single-floor approach: Real-ESRGAN-upscaled Atlas BLP (2048x2048) with 14 hand-pinned bosses.

The 'floors' schema added to dungeon_replacements stays in tools/kg_build_data.py — useful if a future high-quality classic-layout multi-floor map shows up.
