Scholomance: switch to upreza 4-floor 4096x3072 maps for parity with the rest of the picker

Same multi-floor look as every other dungeon: 4 webps with floor tabs (The Reliquary / Chamber of Summoning / The Upper Study / Headmaster's Study).

Each of the 14 classic Scholo bosses hand-pinned to a specific room within its floor:
  f1 (Reliquary):     Blood Steward of Kirtonos
  f2 (CoS):           Kirtonos summon, Vectus, Marduk Blackpool
  f3 (Upper Study):   Jandice, Rattlegore, Polkelt, Krastinov, Malicia
  f4 (Headmaster's):  Illucia, Alexei, Ravenian, Ras, Gandling

Schema change: dungeon_replacements now supports a 'floors' array for multi-floor manual overrides, alongside the existing single-floor 'bosses'/'atlasloot_id' modes.
