Mount Duplication and Reliability Update

Mount Duplication Fixes

• Reworked relocation to find and teleport the existing mount entity instead of creating a replacement.
• Added asynchronous loading for source and destination chunks.
• Added chunk tickets and entity-loading retries while resolving mounts.
• Prevented relocation when the original mount cannot be safely verified.
• Added locking to prevent simultaneous relocation operations on the same mount.
• Updated /ns call and the Call Mount management option.
• Updated command and GUI stable teleportation.
• Updated auto-stable on logout.
• Updated mount storage and market handling.

Duplicate Cleanup

• Added startup reconciliation for mounts in already-loaded chunks.
• Confirmed stale duplicate entities are removed automatically.
• Active mounts have their saved names and tracking data restored.
• Stored or market-listed mounts found physically spawned are removed.
• Ambiguous entities are preserved and reported instead of being deleted unsafely.
• Unloaded mounts are checked when their chunks load.

Mount Renaming

• Fixed renaming mounts located in unloaded chunks.
• Saved names are applied when mounts are loaded.
• Mount names are synchronized during startup and entity loading.

Configuration Changes

• horse-management.summon-cooldown-seconds now defaults to 0.
• The summon cooldown is optional and is no longer required for duplicate protection.
• horse-management.auto-stable.enabled now defaults to false.
• Auto-stable operations remain queued one mount at a time.
• horse-management.auto-stable.queue-delay-ticks remains available to reduce back-to-back chunk activity.
