feat(chat): Add disableChat configuration option

Introduces a comprehensive disableChat config option that disables the entire chat feature including button visibility, notifications, sounds, private messages, and keyboard shortcuts. When disabled, the chat tab is hidden from the chat panel while allowing other tabs (polls, files, CC) to remain accessible.
