NBT schematic loading doesn't spawn entities

[kashiandwazaki]

Bug Description
When loading .nbt schematic files, LimboAuth only loads blocks and tile entities but ignores regular entities like armor stands, items, paintings etc.

Expected Behavior
All entities present in the NBT file should be spawned in the limbo world.

Reproduction Steps

1. Create a schematic with entities using structure blocks
2. Set the schematic file in LimboAuth config
3. Join the limbo - entities are missing

NBT Structure
The NBT contains an "Entities" array that is being ignored by the current parser.
