Visual Mobs Edit

Changes:
1. Removed expert mode page.
2. Updated mob glowing logic to support glowing for all mobs.
3. Added dedicated selection screens for attributes, potion effects, items, enchantments, dimensions, biomes, and blocks to streamline editing.
4. Added support for custom spawn registration (e.g., enabling the Ender Dragon to spawn in the Overworld).
5. Spawn control page now includes spawn chance, spawn range, attempts per second, and global mob limit settings.
6. Mob spawn configurations now support custom potion effects, equipped armor, and main/offhand items. Equipment and weapons support NBT editing and include a built-in enchantment selector.

Notes:
- To make mobs spawn outside vanilla conditions, use the spawn registration feature; biome settings on the edit page remain as filters.
- For boss mobs that need to spawn, enable the "Use /summon" option; leave it disabled for regular mobs.
