Fix live message ordering during chat log restoration

[NineOfGaming]

Fixes #263.

Live chat messages can arrive while the saved chat log is still being deserialized.
Those messages were displayed and persisted immediately, then pushed behind the saved history when restoration finished.

This change queues live messages until restoration completes, ensuring the saved history remains the base and new messages appear afterward in their original arrival order.

• Added explicit chat restoration states.
• Sets the state to LOADING before asynchronous deserialization starts.
• Captures incoming messages and their associated metadata while loading.
• Restores saved history before replaying queued messages in FIFO order.
• Replays messages through the normal ChatComponent.addMessage path so formatting, duplicate condensation, and persistence still run normally.
• Ensures failures cannot leave chat permanently stuck in a loading state.

Also switched TextColor.formatValue() to its public equivalent, TextColor.serialize(), fixing compilation on 26.x without changing formatting behavior.
