feat: Add case format to ProjectSettingsState and fromSelector method to NamingConvention

This commit adds a new attribute, `caseFormat`, to the `ProjectSettingsState` class. It also introduces a static method `fromSelector` in the `NamingConvention` class to transform a string into a NamingConvention enum. The transformation in `ProjectSettingsComponentState` has been updated  to use this new method.
