Implement chat log handler with database support

The code changes introduce the ability to log chat messages. A new ChatLogHandler class has been added that manages the queue of chat log messages, both storing them in memory and writing them to a database. New columns have been added to the database and the interactivity with the database is handled using prepared statements to improve security and performance. The chat messages are deleted from the database after a certain period, which can be configured.
