Moved `NamingConvention` from the settings package to a new settings.presets package. This involved modifying various import statements across the application and updating methods that utilised this enum. Increased the `KeyCaseFormater` minimum and preferred width to 200 for better UI rendering.
Updated naming convention features by simplifying key case formatter construction and expanding the naming convention enum. Also performed a refactor to layout and formatting across various files for improved readability. Added new test cases to validate the update to naming convention.
Implemented a new setting, `getCaseFormat`, in the `ProjectSettings` interface, returning the naming convention used. Also extended corresponding implementations (`DefaultPreset`, `VueI18nPreset`, `ReactI18NextPreset`, `SettingsTestPreset`) to return `NamingConvention.CAMEL_CASE`. A new enum `NamingConvention` was created for this, with options `SNAKE_CASE` and `CAMEL_CASE`.
A new setting, `flavorTemplate` is introduced to specify how strings are replaced with i18n representation. This includes code modifications for handling this new feature and also updates in the messages.properties file for the associated UI text. The feature is especially useful for customizing how localization strings are generated in different project setups.
