ChatLocker

Added

• Added proper Spigot-side handling for Bungee → Spigot chat control via plugin messaging (BungeeCord channel, ChatControl subchannel) to support remote LOCK/UNLOCK.
• Added /chatstatus command to report current chat lock state.
• Added new message keys to messages.yml:
  • chat_status_locked
  • chat_status_unlocked
• Added {sender} placeholder support to lock/unlock broadcasts.

Fixed

• Fixed Spigot messages.yml loading (was incorrectly reading from config.yml), preventing missing-message null values and potential NPEs.
