This is a huge configuration refactoring. The configuration system now uses Pydantic settings, with better validation, better support for environment variables and other goodies. The main config files now use TOML instead of INI, this allow for better handling of complex types, notably dict. Plugins, components and frontends can declare their config settings in a class which will be imported dynamically.
