Add mob-data and mythic-mob custom block types

[tastybento]

Summary

• Adds a new mob-data phase entry type that summons an entity via the vanilla /summon NBT/component syntax (e.g. glowing breeze with a minecraft:generic.scale attribute). Closes mob-data #488.
• Adds a new mythic-mob phase entry type that spawns a MythicMob via BentoBox's MythicMobsHook, with no direct MythicMobs compile dependency. Closes MythicMobs Spawn Possibility #303.
• For both types, MakeSpace runs after spawn so scaled/oversized hitboxes automatically clear surrounding blocks — mob-data schedules it one tick later (to let NBT-driven attributes like scale apply) and mythic-mob passes it as the Consumer<Entity> callback on the new MythicMobsHook.spawnMythicMob(record, loc, Consumer) overload.
• MythicMobCustomBlock uses reflection to detect the 3-arg hook overload, so the addon still compiles and runs against BentoBox 3.13.0 and transparently lights up the MakeSpace callback once users upgrade to a BentoBox build containing the overload.

YAML example

blocks:
  - type: mob-data
    data: minecraft:breeze{Glowing:1b,attributes:[{id:"minecraft:generic.scale",base:2}]}
    underlying-block: STONE
    probability: 15

  - type: mythic-mob
    mob: SkeletalKnight
    level: 3
    power: 1.0
    display-name: "Boss"
    underlying-block: STONE
    probability: 5

Test plan

• mvn test — 403 tests pass (10 new unit tests in MobDataCustomBlockTest and MythicMobCustomBlockTest covering parsing, defaults, invalid underlying-block handling, string-to-numeric coercion, and creator routing).
• mvn package — builds cleanly.
• Manual: install on a Paper server with BentoBox + MythicMobs, add both example entries to a phase, progress an island to that phase and verify the scaled breeze spawns with NBT applied and adjacent blocks break; verify the mythic mob spawns after the hook's 40-tick delay and its surrounding blocks clear.
• Manual: remove MythicMobs plugin, confirm the mythic-mob entry logs a warning and gameplay continues without errors.
