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.
