Add new features: DefaultBrowser, DynamicLock, SandwichReminder

- Implemented DefaultBrowser feature to notify users when the default browser does not match the configured app. - Added DynamicLock feature to disable Dynamic Lock while connected to a specific network and re-enable it after disconnecting. - Created SandwichReminder feature to prompt users to order a sandwich during work hours based on network and time settings. Introduced helper libraries for configuration, elevation, logging, network utilities, and toast notifications. - Config.ps1: Added functions for reading and writing configuration and state files. - Elevation.ps1: Added functions to check for administrator privileges and request elevation. - Logging.ps1: Implemented a shared logging utility for consistent logging across features. - NetworkUtils.ps1: Added a function to check for DNS suffix connectivity. - ToastHelper.ps1: Created a helper for displaying Windows toast notifications. Implemented runner.ps1 as the main entry point for executing features based on configuration.
