feat: add CraftEngineHook for centralised custom block support

[tastybento]

Summary

• Adds CraftEngineHook to the BentoBox hooks system, following the same pattern as ItemsAdderHook and OraxenHook
• Registers it in BentoBoxHookRegistrar.registerLateHooks() and adds CraftEngine to plugin.yml soft-depends
• Adds net.momirealms:craft-engine-bukkit/core provided compile dependencies and the MomiRealms Maven repo

API provided

Method	Purpose
getBlockId(Location/Block)	Returns the namespaced ID of the CE block at a location, or null
exists(String id)	Checks whether a block ID is registered in CraftEngine
placeBlock(Location, String id)	Places a CraftEngine custom block

Context

CraftEngine support was added to AOneBlock in PR #496 using direct API calls. The Level addon (BentoBoxWorld/Level#418) also needs CraftEngine block detection for island level calculation. Centralising the hook in BentoBox means neither addon needs a direct CraftEngine compile dependency, and future addons get the same benefit for free.

Dependent PRs:

• AOneBlock: refactors to use this hook (direct CE imports removed)
• Level: adds CE block counting using CraftEngineHook.getBlockId()

Test plan

• Server starts with CraftEngine installed → hook registers, getHooks().getHook("CraftEngine").isPresent() returns true
• Server starts without CraftEngine → hook silently skipped, no errors logged
• CraftEngineHook.getBlockId(location) returns the correct namespaced ID for a placed CE block
• CraftEngineHook.placeBlock(location, id) places the block (exercised via AOneBlock)
